Hopefully we'll see some more maps with variety in size. I'm sure I'll think of more. There's obviously potential (the mode is built on the foundation of arguably the best FPS in history) but it just needs some more time in the oven to iron out some kinks and polish it up.

Weapons should carry over between rounds (play around with ammo economy/carry over if you're that worried about someone being able to carry over sniper for the whole game). I'm assuming weapons are able to be picked up off bodies, but if they're not then they should be.

I think you hit the nail on the head when you mentioned we aren’t content farming for weapons that may not even be better at all. For me, I have a set of weapons of each element that I absolutely love. Why spend a bunch of time grinding for weapons I’m never going to use?
