Born in Chaos

So after hitting every enrage timer in BT with a couple of different guild runs, I decided to do some research.  It seems that the enrage timers are not tagged to percent health, but are, in fact, based on time.  This means our DPS output is not high enough for the duration of the fight.  I think part of the problem is that both times we had trouble we had someone playing an off role.  I know Bioware wants to allow some versatility in the class selection, but I'm not sure this holds for hard mode PvE.  If you're a tank, you've likely stacked endurance and spec'd for tanking -- swapping stance won't allow you to generate enough damage to beat these timers.  Ditto for healers, you're probably not set up or practiced at sustained high damage output. 

So, I'd just the recipe for happy hard modes is following the trinity and taking two pure dps, a tank and a healer.  Should keep frustrations low and generate less expensive repair bills.  Obviously once we're over-geared this won't be a problem, but just starting out it seems to make sense.
