Try playing Defiance MMO Matchmaking on xbox. Then tell me if no aim assist is really a good idea. It's seriously terrible. You have no idea how inaccurate the controller precision aiming is without aim assist. Want to know what happened as a result of no aim assist? Everyone in that multiplayer game uses shotguns and infectors (the equivalent to the needler in halo) Sniping is a dead-end and impossible, literally near impossible, assault rifles, LMGs and SMGs are NEVER used to get kills, and pistols are altogether completely neglected. What's worse is that the people who play the game use the fact there isn't aim assist to their advantage, they will strafe and bunny hop everywhere so even have you an LMG it's -blam!-ing impossible to keep up with them hip firing a shotgun or autoaim weapon while strafing. You seriously have no idea what no aim assist is like on controllers, if you don't have any games that have no aim assist, go play Halo 1 or any PC game with an xbox controller. It's possible, just plug it up to the USB. Typically PC games don't have aim assist because the mouse is very accurate.
