Ah, OK. That makes more sense.
I like super-fast recharge speeds, they're sexy. I've been planning my MP characters around that with one exception, and I'm a monster pimping just one gun. My Infiltrator really needs the pair, though, especially because I desperately need aiming lessons with ME3's sniper rifles for whatever reason.
For my Soldier in the campaign, though, I think I busted out the Mattock and the Valiant. I'd have gone with the Widow but the weight was just too ugly for my taste... when I do my NG+ with him, though, I'll work it up to Level 10 and take it along for the ride.
