Yes I've used a controller and I was like a Jerry's kid derping around but my time was very limited. Also yes I noticed the youthful hormones and no brain-to-mouth governor which is the reason I always ran right back to my PC. I'm an older guy with a daughter that plays on the Xbox. My 'plan' was to wait 2-3 months and get a 'next gen' (laugh) console. I've heard that the PS4 has native KB/M support but the Dev needs to enable it to be used. I've also thought about a 'converter' but I've seen hate threads about its use.
My thoughts are if I can Mute all of the players I can still play in some resemblance of peace. BO2 was great on the PC but OMG Ghosts is a hack fest and the only, I'm totally serious here, game types you can play are TDM & DOM ... that's it. Last night there were ~4K online and exaggerating low 20% were hacking and some were ridiculous about it, giving new meaning to the term 'obvious.' I'd say I was in 4-5 forfeited games in TDM.
