You sound as dumb as Phil. It's not input lag, the animation for the roll starts the very instant you press the button. I'm not sure of the exact frame data and where the i-frames are. It could just be that the i-frames are delayed, by design. Also the projectile going backwards only happened because the boss was targetting and facing the summon that Phil used, but I guess it just went straight to Phil once it came out. He deserved it for being such a pathetic little pussy who uses that summon shit that shouldn't even be in the game.
