BF3 is a game for people with slow twitch reactions, like myself... and not for the 12 and under run and gun losers on MW3.
Is there a game for people who can't stand playing shooters on a gamepad but who still want the community experience that console shooters provide? Yeah, thought not. Hence why I don't really buy shooters anymore
Wish MS and Sony would just get over it already and let people use KB/M inputs for games. If the competitive thing is the problem - which seems disingenuous since they allow much better controllers for fighting games - then just have an option to play on controller-only servers, KB/M-only servers, or mixed servers, and let the player decide.
