Let me balance this game

[Vanquish]

Well, obviously all CS are rewarding the aim more than anything else

I would say quake rewards aim more since the main hitscan gun has low damage but no spread or recoil. Most CS weapons have spread.

100% different toward AC's gameplay. We can't even compare things.

+1, AC's weapon balance has never been designed with competition in mind (sadly) although I'd argue CS's weapon balance isn't perfect either. Adding random elements such as recoil and spread to a game make the players struggle against the limitations of the game and the unpredictable elements that could fail them at any time, as opposed to allowing players to struggle against their own skill and then ultimately progress and push the skill cap even higher.
