My renegade femshep looks like Mr(s). Freeze, so I find myself constantly using the Avalanche heavy weapon. Unlike all the other HW's, it's not so good for big mechs and the like. It is, however, really fun and effective to use on groups of normal enemies.
I don't understand the hoarding mentality with special weapons though. Use it or lose it.
@endaround: I did a slightly less than grand unboxing. I opened everything up but only got to check out the boxers. They look like they fit me, so that's cool. I would have kept going but my boss came by to discuss work, ruining my fun.
