Im very much the same at the moment, the last 2 CODs for me have been abysmal...
BO2 was because of connection issues, mainly my own ISP... It ruined my experience.
Ghosts, just killed it for me and I've just been playing FIFA, dead nation, runescape and warframe since...
Thing is I want to play games like COD again, I miss the competition, even the banter... Ghosts just has something about it that gets me so wound up I just dare not put the disc in anymore, I want to but keep stopping myself...
I really have my fingers crossed for this years upcoming games, COD and The division mainly to get me back into that competitive style of game..
