For standard MMOs I'm more comfortable with mouse/keyboard... but this game's default setup is so god awful and the lag is just unbearable that I just use my PS3 controller to play. Controller is far superior in FFXIV 1.X.

I'll definitely go back to mouse/keyboard for 2.0 and compare it to the new controller scheme. Theres a lot of things you can do with m/k that you can't do with a gamepad. One thing that comes to mind is:

While running - Jump -> Spin camera 180 degrees -> Disengage (WoW Hunter) - to leap forward in the same direction you were running. You cannot spin the camera fast enough for this with a gamepad.

For those that don't know or just can't figure it out from that scenario above... Disengage makes you jump back like Elusive Jump. <-- this is probably first thing I'm going to try to do and I do think it's possible since in one of the videos you can see him jump then use an ability while falling. lol
