I have a a thought on what should change for Test weapons in the upcoming Rise of Iron Expansion:
1. Stop making the weapons white pieces of complete and total ass.
That's literately it. Just make them rares/legendaries with semi-decent rolls. Seriously, it is extremely annoying to try to get kills with shotguns that 0 range whatsoever, or a pulse rifle that has extremely bad stability. These are not something meant for an achievement, this is busy work for each week.
The way I see it they're supposed to be a challenge. I'm horrible at PvP (just check my stats for proof) and I got through the PvP test weapons in just a handful of matches
