And even so I would still say that as far as class design goes, not even just healer, WoW is by far the better MMORPG.
Just looking at healer?
We'll take Priest alone. Tell me how another MMORPG with spec based design can make Holy Priest and Discipline Priest feel and play completely different,
yet AST and WHM here in FFXIV functionally play exactly the same because SE can't be half arsed to make AST into a complete Heal over Time Healer now that its lost its hybrid identity of shield/pure healer simply because "learning how to HoT heal over burst heal is harder for the average player".
All of AST and WHM's GCDs are the same for no reason. Celestial Intersection and Divine Bension are the same for no. good. reason. And AST already has been set up in future abilities (Exaltation, Macrocosmos, Earthly Star) to have a completely different heal style that the other healers do not have (delayed healing) why not fix the rest of its kit to reflect that?
And that is just a small part of the issue I have with FFXIV's healers.
And no. "Go play WoW" isn't an answer to the argument because
1. AST and WHM actually play differently in PvP
and 2. It doesn't fix the problem the game actually has: their class design needs work.
I wouldn't care if dungeons were piss easy if I found classes in the game to be fun regardless of it.
