Okay, so i checked wowhead a couple of hours ago, and came across Bastion of Twilight trash mobs somehow, and i noticed that the trashmobs in the start of the instance (Soul Blades, Dark Menders, Crossfires and Shadow Knights) all had 2-5 epics whom could drop off of them, most of which had 2-5% drop chanse per mob as well, so i stacked up all the epics and their percentage and did a slight mathematical calculation. The results shocked me abit, it was about 10% drop chanse PER MOB for an epic item to drop.
So i talked to some people and a friend of mine had recently been inside the instance and cleared trash for and resetted after the first 3 packs for an hour and a half or so. He had gotten 5 epic items during 1 SINGLE RUN. Atleast he said so, i've got no direct proof though.
So i made a grp myself, got inside, and after almost 6 clears of the first 3 packs of mobs, it had only dropped 1 epic item (Crossfire Carbine) So i figured 14 x 6 = 84, so for almost 1 and a half hour we had about 1 to 84 drop chanse. Hence i wonder, what are your experiences? Can we perhaps get a little debate going about the current drop ratings and how you guys have experienced the trash-farming in Bastion of Twilight (Or Blackwing Descent for that matter)?
PS: This is all information from 10mans, i don't know the current drop rate or anything from 25man.
