I click. I am happy with clicking. I have no issues with clicking. Noone has picked me up on performance in PVE or PVP. I have tried keybinding but feel more comfortable with clicking. I suppose its just whatever you feel more comfortable with - at the end of the day its just a game
Well, once you get comphy with keybinding you will see an increase in whatever skill you have. If you are a long time clicker, of course it won't be comphy at first, just like anything you have to get used to it.
