There always seems to be a group of people that prefer playing with the keyboard and mouse that troll this topic, bullying everyone to play the way they do like a bunch of Nazis. Honestly, if you like playing with the KB & M good for you! What are you complaining about the game already fully supports the KB & M. Its not like Bohemia is going to drop the KB & M all of a sudden in favor of gamepads. The point of this thread is for people "who use" gamepads to voice their opinions to get the developer to take notice, not waste our time trying to justify the existence of gamepads to a bunch of bigots who can't seem to accept that not everyone plays games like them.
Like many others I started off playing 1st/3rd shooters on the PC with a KB & M and began adopting the gamepad as console shooters were becoming more popular. Now I play all games with gamepad unless its an RTS where KB and M are necessary, I find that I can play a game for several hours without having any strain in my neck or arm afterwards. Sure, the mouse gets more accuracy and faster twitch reactions and I will probably get whooped by KB & M players everytime in games like Call of Duty where reaction time is everything.
Anyway it is becoming an industry standard these days for games to have full gamepad support and even though I like the fact that Arma has a lot of complex functions that you don't normally see in other shooters, that still should not limit the games accessibility from a streamlined control scheme where the basic gameplay mechanics are fully supported on the gamepad.
