-Make RDM Relevant
-Stop nerfing SCH every time it becomes remotely useful
-Make SMN useful
-Make PLD able to perform the role it is supposed to excel at better than 90% of all melee jobs that currently do it better
-Stop making content that requires an alliance of Relic/Mythic and barring those, at least lvl 95 Emp to succeed
-Do away with AOE that can 1 shot most job/race combinations
-Stop implementing abilities without enough testing to determine if they will be overpowered
-Combined with above, stop nerfing things years after the fact because you "never got around to it"
-Get rid of luck based rewards and drops. Reward work and effort.
-Ban everyone that complains about Abyssea xp - it's here to stay goobers.
-Fix tp loss from "too far away"
-Stop nerfing a job that suddenly becomes "up to par".. provided it has a lvl 95+ Relic/Mythic.. lol
-As with above, stop making WAR and SAM the only relevant DDs.. it sucked in 2007 at merit camps and guess what.. it still sucks.
In short, and in response to requests for better marketing of the game:
-Fix the game first and then market a working, if not dying product to John Q. Public
