The only reason I use Retriever is because of the level 2 bonus for requiring 1 less dog tag

But the other modules are much more useful
Besides, using support bonuses is cheap, I don't like them, they should be removed completely
If support bonuses would be removed, you could trow the Multiplayer away... The killstreaks are awesome!
pffffff, tell that to someone whos been playing pro mode 99% of the time. They're alright, but nothing necessary
