I've been playing MW3 recently. I was playing BO2 up to about a couple of months ago because all of a sudden I was 1 bar-ing and playing in stop motion every game. Before I could go 7-10:1 ratio easy as and get really close to Nuclear but after my connection went to the pits I couldn't play at all. So I switched to MW3 and that was just as bad. I remember getting an Osprey Gunner twice while 1 bar-ing and that was crack-up, but then i would start playing in stop motion all over and it got way too tiring. So then I changed my NAT to open and disable DLC and ever since I've joined games faster that I can connect to way better than before, like I would be 3-4 bar every game. I managed to get 5 more MOABS within a week like this and it really improved my game. I might jump back onto BO2 soon when I have some spare time. If I recall rightly I'm still using:
MTAR w/ Silencer + Stock
And the Tier 1 perk wildcard
I want to try and get the Nuclear Title with the MTAR before I move onto another gun/prestige it so that'll be a goal once I jump back on. I've gotten Brutal twice with my highest streak being 27/28, so hopefully my connection woes will be gone with BO2. I prefer to use the EMP over the CUAV since it destroys enemy electronics which is great since I'm not running Blind Eye anymore, and I think you get more EXP as well? But yeah, definitely looking forward to playing again asap.
