What TomekC said, If you want the best exp go do manual bounty's and stack a few pools of reflection first. I however am running the so called 'elite pack' profiles, Not only do I get legendaries but I get pretty damn good exp too. I stopped running cota profiles to stack 100-150m pool bonus exp and its still good, its FREE EXP WHILE DOING NOTHING otherwise. I turn the bot on while I am not at the computer or away, it gets me legs + paragon levels/gold/salvage mats whatever. When I want to play I go and do some bounties with friends.
