Im gonna support éclipses hère.
Just yesterday I was doing susano.
when dodge the water puddle after the rocks. I went to the other side of the arena and ended up dying in the middle of it because the game considered I was still in it. We are talking a good 3 ley line diameter away from the puddle boundary which the game didn't record. I'm not even talking about weaving skills too fast and ending up loosing cards and getting no buffs.
People can call lag or wathever, but I don't suffer something remotely close in any other game no matter which server I pick.

Ff14 with 50ms is actually more clunky, lag wise, than wow with 400-500ms, and I've raided every WoW end game from BC to Cata so I know what dodging a telegraph is.
