Best no stacks run I have found so far... witha fast moving char.

Korsikk and run the inner ring picking up mobs to follow you, bring elites.

1m a run, 1 min a run if you practice it.

could get faster with variables, I only use helm gem.

You kill masss mobs at the end of kite circle with 3-5 elites in seconds.

reset.

Just fyi. other a3 areas dont have the mobs per sec this does.
