Really now? Over the past few months I have seen wonderful ideas on how to properly balance jobs and events in this game that SE has never payed attention to. I can give some myself right now.
PLD - Needs an AoE attack (Needs Circle Slash back.), needs more oomph on enmity generation abilities on a large scale.
WAR - It is fine now. SE gimped it but we played with it last night and still a much better tank than PLD. I wouldn't consider a WAR tank OP anymore however.
BLM - I know people will grab the pitch forks and find which window in my home they need to break into, but I do believe BLM's need to be toned down. I mean in particular their AoE damage. Fire damage should spread depending on how many enemies get hit by it. How OP is it you can go into a dungeon and just take a few BLM's and kill all the enemies in a room in a matter of seconds before a melee can barely hit it?
As for dungeons. The idea of speed runs is the core of the problem here. Not to mention the abysmal drop rates. When people are forced to speed through the content as fast as possible at a abysmally low chance of getting a piece of gear with only a 15 minute cool down, of course they are inevitably going to find the quickest way of doing it. It is because they are sick of the content, they don't care about the dungeon itself anymore, it is all about the treasure chests at the end now. I don't know why other MMO's know exactly how dungeon content should be distributed but SE can't get something so simple right.
For bosses, they just really need to tone the AoE down. The biggest problem with Chimera is that it is just not melee friendly at all. Poisons and his AoE potentially instant kills whatever is near him. How do you expect WHM's to keep up with this? You are practically begging people not to use melee in this fight. Chimera is the most unbalanced boss fight I have ever gone against in my MMO career. Sure have AoE in there, but AoE should never be bad to the point that it isn't practical to be near him.
So if you want to make bringing melee and PLD viable, you really need to adjust the conditions of the dungeons. Speed runs screw a lot of things up.
If anything, I wish Darklight didn't drop in dungeons at all. Would be nice if it was just setup that you got points at a dungeon and you got a daily cap on how many points you can get and have a NPC sell you Darklight. This works in other MMO's, don't see why it can't here. You can get more points a dungeon run by setting conditions (Kill Marshall after Princess) or (Lure Chimera into a sandpit three times). Can still do dungeons if you hit the cap, but just won't be rewarded points (In case you wanted to help others). I would put at least a 30 minute timer on the dungeon so it is an incentive not to spam one dungeon, but alternate between AV and CC.
So Char, after all this, rather you agree with my ideas or not, it is still my attempt to help this game go in the right direction. Not all of us just come in here to whine, some of us use these forums only as a way to give developers proper feedback they seek. Rather my tone sounds frustrating or not, I strive to give feedback whenever I can and hope that developers will take into consideration my ideas.
