Has anyone noticed the huge XP pay outs on the weekly challenges? Just did the 2 spartan Ops challenges which was easy because spartan ops is fun as hell now. Completed both challenges on 2 maps. Episode 5 chapter 5 and episode 7 chapter 2, I did it solo (normal) and there are more than enough of each enemy type on the levels.
So for doing both levels I got 30,000+ XP
anyways Just thought I would bring this to your attention. Have fun
