Comparing a PC shooter to a console shooter is like comparing an F1 car to a Rally car. Sure one goes a lot faster but the Rally car was designed with different objectives in mind. Both F1 racers and Rally racers are equally as skilled but in different aspects of driving. The same thing is true for the KB+M/gamepad argument. Sure one is faster but console fps are not designed around twitch play. If you look at the top console FPS pro's playing you see that the game revolves significantly around team work and map control.
Also your claim that you played Halo:CE multiplat is complete and utter bullshit. XBC was a system link tunneling device, I would know since I played almost every day. There was no way whatsoever so play Halo:CE cross plat so don't make up shit to make yourself look good.
