COD has always had a toxic community in general. I've had some negative experiences with CAG members in the past. I realized it was nothing personal, it's just the culture around the game in general.
I've had fun with COD for the most part. It's what brought me back to online gaming after so many years off, but now i enjoy the BF and Destiny communities better. Just more good feels.
I'm not ruling out getting this new COD but i've played it a few hours on someone else's account and i could feel that old rage creeping up from lag compensation kills, weird hit registration, etc. I know it happens in a lot of games but i just wasn't feeling it this time. Maybe when the price goes down in the new year, before Hardline comes out.
