I was dreading this weekends challenge just because I have no good weapons or my good ones are still rank 1 or two. Pretty much reager carbine, valiant, and black widow are my 3 best weapons (the cerberus pistol and carnifex for those but I only use those on adepts and don't count them as part of their kit) But it was fine and was mostly thanks to my team mates that made a Ghost Reaper Gold pretty easy.
Of course I was playing an odd shotgun choice as a female quarian engineer. But the turret and the slow from cyro helped out a bunch on brutes/banshees. I just wish my packs upgraded or gave me good weapons instead of upgrading the weapons I never or aren't as good as weak versions of other weapons. Mostly though I want the new sniper rifle cause I pretty much play mostly sniper builds but I think I'll fit the carbine in even if its still rank 1
