The thing is you have no casting time in FF13, so if you did Death which took up 5, you only had to have a full bar and pop it'd do Death

In FF14 you have a casting bar so for a mage its
- Need enough MP
- Need enough Stamina
- Now wait for Cast timer
- Now wait for recast timer

I understand most but why do we need to wait for a Cast timer and a Stamina and have enough MP, it all seems very restrictive. If I have the MP, let me do the damn spell. And now I can since its removed. If I want to do blizzard and I have enough MP, I can do it and it can start casting right away, not when some bar says I can.

You think it gave you control, but it doesnt.

Also removing it is completely different thing than adding in Auto Attack, they could of removed Stamina and not had auto attack and vice-versa.
