I am sorry but you are way off on Black Talon. I ran it yesterday with FRESH 50ies, we didn't hit enrage timers on ANY of the bosses except for the bonus one, who went down anyway. We had a madness sorc (me), merc healer, sniper dps, jug tank.
Wouldn't say I'm way off when you actually hit enrage on one and was probably close on last boss too. The enrage timers in BT are fine if you play well, but as I was trying to imply, I think they will be a tad too punishing for people who are somewhat new to the game. Compared to certain other enrage timers though, they are pretty softball.
