Please stop trying to make this FFXI-2!
I love the way this game is. It needs improvements, it is not without it's flaws, but we do not need to go BACKWARDS to improve the game. 10 year old mechanics do not work. You don't make the game more fun by limiting, forcing or taking away freedom.
All FFXIV needs is more flashy effects and emote type animations (big variety of them) for skills to make them look cooler and be recognizable.
FFXIV Also needs challenging content and group gameplay, like missions and instances/dungeons, quests, monsters and whatever else you can beat with a group and feel good about.
The future of MMO is stepping away from the 'Holy-trinity' not going back to it.
Just saying from your title 'back' is wrong... Forward is the answer.
