-"Out of range" while playing a melee class was ridiculous in FFXI a decade ago. The fact that you can still chase after certain things at the same speed and not be able to activate abilities must be fixed.

-Casters should pivot to face moving targets as they cast a spell. You can bind a key to turn your character as you cast -- there's no reason that this shouldn't be done automatically.

-1, 2, 3 combos are boring and way too present in FFXIV. Combos should reduce TP cost, not increase damage. If I want to use Rage of Halone 3 times in a row for full effect, I should be able to. The consequence should be absurdly inefficient TP cost.

-There is next to 0 interaction between team mates during battle. There should be some system to test coordination between team mates that is not fight mechanic dependant.

-Damage of Time spells need to not combine and be clearly marked. It is far too difficult to tell how DoT clipping is affecting your DPS. I can't even tell how much damage my DoTs are even doing in party settings because they just roll into everyone else's.
