Quick horde camp question

My guild is 4/5 in Hyjal but we're still trying to nail down the smoothest strategies for all the bosses. One thing that we've found a bit of a pain is the way that kaz and azgalor enter the horde encampment. They pretty much immediately aggro the NPCs at the entrance forcing us to start the fights before we have drunk, repositioned and buffed. Yesterday we lost about 45 seconds at the start of our Kaz kill when a MD wasn't enough to pull Kaz off of the NPCs at the entrance and our whole raid had to reposition and run down as the timer on the marks was already ticking.

Do other people let the NPCs at the entrance purposefully die during the trash waves? Or is it possible to let the boss kill the NPCs and then have him reset and be out of combat once they are dead.

Yeah 1/2 way through wave 8 we have the rogues move out down the path pretty afar and wait for the boss. They distract whlie we get setup and then we'll call out MD when ready and the bosses shoot right past the NPCs then since the rogues keep the boss out front pretty far.

I've tried this on the trash packs at the entrance to the alliance camp but they were all immune since they were "in combat". I'll have to move farther out of the encampment tonight and try again.

trash can't be distracted. The bosses however can. It may get resisted and you may lose a rogue then, but it's all up to how badly you need those extra 20-35 seconds he can buy you.

Just stay way in back near Thrall. When the boss kills off the NPC's up front, he'll reset and start walking slowly again, thus resetting your timers.
