stick with mouse + kb. the gamepad may be more comfortable. But, the targeting isn't the best and you have access to more abilities at one time using KB+Mouse.

You can be more precise with your camera using a mouse, you can tab through targets easier as a dps, you can use f1-f4 to target party members as a healer, or you can just click on peoples names or click a target with your mouse pointer to get the target you desire. mmo's require people to dodge things and do as much damage as possible in a set amount of time - the kb+mouse will be the more efficient of the two. That being said -I know ps3 users who play the game just fine with a controller. But having used both, and being a pc gamer for almost 2 decades now, I will say that without a doubt the kb+mouse is superior in terms of accessibility of abilities and target selection. I've honestly been considering plugging my g13 back in for this game, as I used it in WoW.
