Tried going into IB twice. Just couldn't be bothered. Bottom line; its not fun. I look for 2 incentives to play: 1) good loot and/or, 2 ) good playability. What i found was lag/ guys immune to damage, near indistinguishable level differences, and crappy loot. I may try a 3rd time tomorrow if I don't have anything else to do. Not likely though.
