I play on PS3 and have absolutely no problems whatsoever aiming/firing my Flaming Arrow move. I bust it out with perfect accuracy in the perfect timing halfway between my GCD respawn just like any other instant skill. Please refrain from categorizing "all controller" players into one or two instances you may have been been subjected to. Thanks!

Btw: I have about 5 rl friends in my FC who use the PS3 controller on PC because many aspects of it are superior to PC. I.E. General movement, switching between hotbar skills.
