real talk.
I changed all my classes to have OMA. 6 matches, 6 AC-130's, could have gotten the nuke too if it was one of my killstreaks.
bleh. I'll rather use scavenger, since every time I try to use one man army so guy just takes me out. nice to hear you like the AC130 though, all of my buddies use the darn chopper gunner.
Yeah I'd say the two best tier 1 perks are scavenger/OMA, but with OMA you can reload your ammo just like in scavenger (although it takes longer), so I just use OMA. Plus I like OMA since you can change do whatever you need. If someone calls in a UAV/harrier/helicopter, then just switch to a cold blooded class, you can use claymores/tactical insertions without having to sacrifice grenades, switch to a sniper class if you get to a good spot, switch to a class with hardline when your 2 away from a killstreak, etc, etc. Really if you use it right, the advantages of OMA are greater then the disadvantages of losing your secondary weapon.
And I pick the AC-130 over the chopper because everytime I use the chopper gunner it always seems to get shot down after only 3 or so kills :\
I still use bling most of the time, like holographic anf FMJ on an assualt rifle.
I don't really use sights too much unless I'm using the FAL or F2000
4/6 of my classes have OMA. So much greatness.
Sniping? Done.
Cold-Blooded? Done.
UMP? Done.
M16/AK47? Done.
I am really addicted now.
I prefer Bling but I might try OMA on several classes.
