Recently TESo is receiving a lot of credit for making Crafting an important part of the game,if Square is not looking at this ,they SHOULD be.
Crafting needs to be improved and gear progression removed.Gear items if level 50 should remain lvl 50,we don't want to follow the mistakes FFXI made Abyssea and post Abby.

Another idea of note is player skills/spells/abilities.I am constantly hearing there is not enough,it makes for bland combat and NEEDS to be spiced up.One suggestion is to lose the party LIMIT BREAK and give the FUN back to each individual.Perhaps a 1 hour ability or heck let's make this game FUN,give players some nice powerful special attacks or abilities with 20 minute timers.

HOUSING :Other games are introducing USABLE housing,that means players can actually use it at an early stage without having to grind for years to get it or to rely on a guild house,which is NOT your own.
