Suggestions and Improvements To the Game From a new player

[Sedalia]

Tanks

I can go on and on about how powerful Paladins have become when a tank is so powerful in tanking and DPS that they don't need a healer or single party member to solo a boss in a dungeon equivalent to their own level. I think this needs to be addressed. I understand giving Paladins giving more DPS tools was a good idea but giving them too much is a bad idea. They also feel that Warriors and Dark Knights need a little bit more love. They do a lot of damage but when it comes to Savage Content they can't tank it. Surely not like a Paladin or Gunbreaker can do as well as having taking stats that don't seem to make sense other than for fillers. Similar to healers and piety which isn't bad per se it just isn't a priority.

Actual things they would like to see in the game with regards to quality of life changes
First Chocobo carriers should be removed or changed to Chocobo quests player can do to help level up their feisty Chocobo somewhat like Leves which you can only do daily but with the Chocobo music playing. Of course, we don't want to make Chocobo stables unusable so perhaps using some things for the stables for FC houses to compensate for their changes such as more and different types of food you can feed your Chocobo for abilities. Also, revisiting the Chocobo levelling system when you max all your levels to 10 will give you a skill tree you can level up by feeding them rare fruits the seeds of which come from rare boss fates.

Perhaps the chat system could be updated a little and a little love. As an RPer, the ability to mistell is easy to do and this gets people in trouble with others because you have said it in the wrong channel. There should be measures taken to update the chatbox window which stops people accidentally doing this.

I love this game, do not get me wrong, but there are a few things which I hope they will change.

Warriors and DK cannot tank savage content?

Pardon me? Tanks in ShB are the most balanced role, they can tank everything and everywhere if you know how to play your job. Doesn't mean there is nothing to improve, but survability is the not the issue we currently have.

I think people have your proposed class changes covered so I'll just comment on this:

...quality of life changes
First Chocobo carriers should be removed...

I'll grant you that these are not used very often, but they are used. There is a point early in HW where you'll probably want to use one. Rather than removing them completely, I'd much prefer to see the places they can take you expanded, so they're more useful.

...perhaps using some things for the stables for FC houses to compensate for their changes such as more and different types of food you can feed your Chocobo for abilities.

We have this already. There are foods to increase your choco's xp gain, increase healing and increase dps. These can be bought off the MB or grown in any garden if you have access to one. Feeding any of these foods to the choco 10 times in the stable makes it his favourite food and that will increase the benefit when you use the food in the field (choco can only have one favourite).

Also, revisiting the Chocobo levelling system when you max all your levels to 10 will give you a skill tree you can level up ...

And we have this too. Max level is actually 20 and you get there by feeding the choco a Thavnairian Onion each time it reaches a new level after level 10. You can get 2 onions via sidequests and you can buy them off the MB or grow them in a garden. Growing is very involved and will take some time, though.
The skill tree is there as well and you should have been choosing skills for your choco already (assuming it isn't still level 1). You can choose to concentrate on healer, dps or tank (choco tanking isn't great though). When your choco reaches level 20 it will have all the skills from all 3 branches. You get a barding set every time you max out a branch so by the end you'll have 3 sets (these are auto unlocks, each set just appears on the barding list).

Mistells are part of MMO life I think, and I've made quite a few blunders in my time. However, if you r.click the person you want to send a tell to so their name appears in the text box and then press enter before writing anything, this will open up a private channel for you where everything you say will automatically go to that person until you select a new channel.

Hope that is helpful and glad you are enjoying the game.
