They did away with "Insider" when they introduced some of the not-so-recent changes. I wish they would bring it back.
My "boss" was built for leveling. The higher your health, the more XPs you get per win. Some of the guys in Black Ops and others that I stay in touch with have stupid health numbers, I mean 12K plus.
One of my original level partners is up to level 3600 at this point. I stopped leveling when it was taking 10 mins per level. I couldn't use "I'm just sitting in fron of the tube" as an excuse anymore.
I may start it again, as I am getting 140xps per win off the fight list. Optimized with a partner I can easily hit 160plus. My XPs per level have dropped from 8K to 6,900. Really want to hit Tokyo (1300)...
