Change, Remove, Add.

[Pence]

You can change, remove and add a feature/event/anything. But you do need to justify your answer to some extent. Go.

Change: Raids into a single instance. At the moment it does not feel like we're 'raiding' a place, more just.....being warped into a dislocated zone.

Remove: Diadem. It's horrible. A prime example as to why SE needs to have test servers, nothing about this worked. It was an interesting idea but lacked.....everything? Yoshi already demonstrated he could create a balanced synergy between DoWM/DoH in battle with Hamlet 1.0, so not sure what happened here.

Add: Dynamis. Borrowed from from XI. It'd be neat having an event set during the 1.0 invasion of the cities (Those that were not present: Ul'dah was a hot mess. And it was fun AF.). XI was interesting because you need sleep certain mobs, focus others etc etc. It'd bring CC into XIV in a meaningful way, and it's kinda fun beating up everything ever. Also would be a nice throwback to have Dynamis currency.

Change: I'd make the "split" zones (East Shroud, Central Shroud, etc.) whole again.

Remove: Flight. I've long been an opponent of flight in fantasy MMOs, and while FFXIV does a better job with implementation of it compared to the most immediate comparison (WoW), I liked the Heavensward zones best when I couldn't fly, as they now feel no larger than the ARR zones in practice despite being massively bigger.

Add: More gearsets at the highest item level for each raid tier (so, to use current item levels, I'd add at least two more i210 sets for stat variety and also glamour potential).

I think they should change diadem to work like abyssea, where you work on pop items to pop larger NM's which allow you to pop the next tier and tier has its own drop table. Add the !! Triggers would be great also, I would also add the buffs you that you could buy but make it where you use GC seals to buy them. I'll even go as far as adding a way where if your GC control the area your cost of buffs is lower. But don't remove it revamp it the potential is there but SE is playing the safety first game.

I agree with everything else you wrote

[Kaurie]

Change: Almost all of the jobs to remove useless complexities for the sake of complexity (enochian, positionals, minuet) and replace with more complex encounter mechanics

Remove: The line in ToS that says we cannot talk about parsers - first rule of Fight Club n all

Add: More engaging raids that are more than just boss fights

[Houston009]

Change: Odd number patches to no longer be catch-up patches. More intriguing content.

Remove: SE's desire to make everything irrelevant 3-6 months (sometimes the day of release; see Bismark Ex) after release. Longer lasting content

Add: More staff to SE's development team. Rid the excuse of understaffed. Also add more bosses/floor to raids, more raids in general that are not /faceroll, and/or more open raids that also drop recipes/useful resources/useable items/etc something more than just gear.

[AstralKaos]

Change: The glamour system to be a glamour book system.

Remove: Alexander because the boring story, ugly as hell equipment, uninteresting fights and utterly mediocre level design should be forgotten until the day the dev's figure out how to make it the opposite of what I just listed.

Add: The Warring Triad as the raid instead, because three raid stages (if they set it like that again) with one of the Triad for each stage, already interesting story, beings of utter mystery and unfathomable (to us) power sounds like something that should have been the HW raid instead.

[Anienai]

Add more shaved Mohawk hairstyles.
Add a cooler looking stance for Dark Knight.

I really like this idea!

Change

Diadem. Party set up changed to 1 Tank, 2 Healers, 4 DPS, 1 Gatherer. Notorious Monsters would now be force popped, and would be for the single party to defeat, no more Hunt style zergs. Pop items would come from various chests, as well as gathering. Stealth to work again. Gathering would now be in fixed locations, rather than flying around the whole zone. Gathering itself would create "noise" which will attract stronger enemies, meaning having a gatherer is a boon to your group. The treasure chests gatherer's can find will also now produce Temporary Items. Powerful potions/etc. that exist only for Diadem, you cannot take them out with you. These would help speed up combat and make gathering somewhat of a support role. With force pops, the caves in Diadem would now have more importance, with stronger Notorious Monsters being located there. The caves would be blocked however, with rocks/roots. You can engage these blockages in combat, but they have strong defense so that would take a while. Gatherer's, however, can harvest from these blockages, and successfully doing so will deal damage to them. Gathering is thus the most efficient means to remove the blockages and explore the caves.

Remove

Vertical progression being the central pillar of this game. Wiping the slate clean every 6 months is not only a determent to this game, but it is a gross waste of development resources. Developing around this idea means they constantly need to make new stuff to replace the old, and IMO the slip in quality is started to become quite apparent (compare Alexander to Coil). Content should have a much longer shelf life, getting two new dungeons to replace the two old dungeons just gives us four shit dungeons. I'd rather they invest time in content that lasts. See: Diadem changes.

Add

Final Fantasy IXs AP system for special stats on gear. As suggested here.

Screw the rules, I want to change two things

Trials... Stop giving us static circles to fight in... I'm sick of it... Give us battlefields with something else to them... Take Leviathan; That was just Titan at Sea World. Same falling off mechanic. Snore. Lets slap Leviathan in an underwater grotto instead; You fight his head by a pool, with some other pools for his tail to poke out of (similar to Sasatash Hards Kraken fight). Phase one has you doing that. Then you get the the "heart phase" (sticking with Titan), during this phase the cave starts to flood, and you need to escape by running through what amounts to a mini-dungeon. During this phase, Leviathan will attempt to trap you, and you have to DPS his belly to get him out the way (DPS check, same as Titans Heart really). Can also be some adds and gates and so on. Finally you get out of the cave, and you're on the shore of a small island, and the real fight begins, phase 2s music kicks in and you've got the real fight ahead of you. Trials like that would be far more memorable and fun than the "Fight in this circle" instances we've been constantly getting...

Screw the rules, I want to remove two things

Cross-class skills. They're dumb. How silly is it, that my Lv60 Ninja can enter a Lv30 instance and not do Death Blossom, but some Lancer can set it and have access to it? Very silly, that's how silly. Death Blossom isn't even good.

Screw the rules, I want to add two things

5 new Job skills to replace the loss of cross-class skills. Lets face it, there is no real choice involved in what you set. Keep the same general idea of learning from a different class, but slap it in the quest. So my Ninja wants a self heal? Well I'll need to have finished the Pugilist questline to access a quest in which, with the help of the Pugilists, I learn my own form of Second Wind. And so on.

I really hate casting Blizzard II on Summoner, what can I say.

[Melixy]

Change: Character customization. Unlock features such as scars, tattoos, hairstyles for all races and genders.

Remove: Diadem. I don't really want to AoE down regular mobs for an hour and a half in hopes of grown up Littlefoot eventually showing up to cast an ironic meteor onto our faces.

Add: Self-parser on console so the DPS in my static quit asking how much they're doing all the time.
