Onyxia definitely DB more after the patch!
actually, i'm a brand new lvl 50, and my friends and I tried BT hard mode for the first time (for all of us) last night, and was very rudely shown the fact that we're horribly undergeared for it. enrage timers galore.
for those that are essentially farming hard mode stuff. what was your gear progression once you hit 50? was it crafted? did you run the lvl 50 normal FP a bunch first?
how tightly do you think the encounters are tuned atm?
