Hi again

An Enemy in Arthas quest - This quest is avail. as we enter the Pit to do the 2 Quests Marked for Death - High cultist Aangus and Black Blood of Yogg-Saron. Would it make sense to get this quest before starting those two as you are going to have to kill the mobs around the Black Blood samples? I feel that would save an easy 10 min. if you did.

Thanks.
