I don't mind cloaks or jetpacks.
I don't mind piss poor guns or whatever.
Let's just say my main complaint with BO2 was its lag comp. It was heavily noticable when I'd play a game and kill someone with 2-4 bullets of my AN94, and then for the next 5-10 games it took 6-10 bullets, if not half a clip.
I've played every CoD except the last one, and I only played a little of MW3 (Still got a cool 1v6 SnD Clutch though, wish I could get it off my upload from it!)
I don't mind working with new tactics or equipment. It's all about registration and consistency. I nearly broke my WaW disc because of how horrible that game was in terms of registration, and BO2 was bareable at times.
I suppose if it's like BO2's reg, it'll be bad, you just can't play competitively. I think the worst part about COD these days is that, as a competitive player like myself, you'd love to play it competitively, but you're always reminded that even if you go 100-2, it means nothing because there's literally a 95% chance everyone else in the game you're in can't hit worth shit.
MW2 was poor at times but was bareable. I'd like to see that some more

I'll possibly get this in a few months then, but I think I'll finish some other games of mine. It seems like this will be another "casual" CoD. MW2 was the last competitive one.
