They should award extra cR if you switch to the enemy team to balance it out.

So far my least favourite map/gametype combo is 1-flag on Powerhouse. Headhunter is a cool idea but it gets frustrating. Picking up any skulls makes you a huge target and you just end up getting killed after all the work you did killing the first guy. It's really hard to get the skulls then make it all the way to the drop zone safely.
