The BAF was my favorite iTrial, and I think it was mainly due to the Prisoner Escape section in the middle. Reminded me of a Tower Defense game, with all the players as the towers. For that reason, I loved it even more with characters who had location-targeted powers and/or additional pets (like my Bots/Storm MM, Stone/Ice Dom, and Grav/Elec Dom). I was looking forward to trying it with my Thugs/Traps MM, but I didn't get him to 50 in time.
