@shadowstrike: I've never seen something like that occur for humans. They keep obliterating everything in sight in my games.
I've seen one game where nightelf did ok with a mass huntress strategy. Still investigating though.
Edit-I can't run your replay. Can you upload the DE u used as you must have changed something for me not to be able to run it.
Edit2- It dosn't matter I think i know what the problem is. To do with the fact that the units used for pathing checks are in fact wisps :P
