I support auto attack 110% in FFXIV.

Reworking the battle system to have your basic attack to be on an automated interval would do wonders for this game.
You can include guildpoint purchased skills to be basic attack upgrades such as "Pierce". For cases like "Heavy Thrust" you can leave it as is since the bind is more situational.

Auto Attack IS coming. The discussions should be more centered around HOW should it be implemented rather then should it be.
