made it all the way to last boss

I did a guild run of Vanilla's BWL with my guild, mostly 85s, a few 70 and 80s, so we had 10 people exactly, which was enough to count for a Guild Run in BWL since its 40-man, euwowgold.fr made it all the way to last boss, and our lvl 70 Hunter died (new to raiding), and released corpse...which of course put her OUTSIDE the raid, and as luck would have it, we killed Nefarion as she was running back, but there were only 9 of us actually inside the instance, so we didnt get credit for a Guild Run.

So yeah...it CAN be very annoying in some aspects.
