CON is bad *** now, you can que up spells faster and basically always be casting.
Aero is instacast which is freaking awesome.
Just did a FATE with a huge Ochu and DOT's stack now, multiple Aeros and Poison Arrows on it at the same time.
I don't like that you can't pick your starting city but that makes sense for the class quests. I hope Duty Finder can warp you to dungeons otherwise all the healers will be LFG at Grid's dungeons while the Tanks are at Uldahs
Oh and interrupts aren't nearly as often now, I think I've only been interrupted a handful of times. Edited, Jun 14th 2013 7:18am by Wint
