Change "animation locks" (makes the game too slow)

[Remus]

The majority of global cooldown MMOs out there are just 1 second faster (oh, that is sooo much faster /sarcasm) and aren't designed around fitting 1-2 abilities frequently in between that 2.5 second base cooldown.

You would be surprised how much faster it actually is and what difference it makes. It is quite noticeably faster when you have played a MMO with 1/1.5 GCD then switch to FFXIV. It's why its one of the main complaints with the game being slow and asking to decrease the GCD.
