What are the largest issues plaguing XIV currently?

[Shurrikhan]

Lucid Dreaming is a nice way to restore MP during those times your healer has been going full-damage-mode during a personal duty.

Except, again, what's its actual gameplay? An auto-clicker does the job just as well as an "optimized" use of the skill. It could just... not exist, with an additional 350 "Refresh potency" generated per minute instead, and there would be no difference. It's just bloat.

It doesn't have to be bloat. Equilibrium worked perfectly fine in giving both TP or HP when needed. For example: if PLD's Clemency gave TP in Sword Oath stance and HP in Shield Oath stance you have one button that performs different functions and also gave you the player a 'choice' in what to do when in a situation. Choice, is also something that this game is slowly losing in favor of balance.

Forgoing nitpicks into those particular examples... Agreed. MP, TP and their relevant abilities don't have to be just bloat. And I'd rather use both TP and MP than merely scrap those mechanics. But using them required that those mechanics amount to more than just a button you (auto)click every minute.
