Dark Eldars were awesome. Amongst their ridiculously powerful weapons, they had modern blowguns which fired venomous darts at other characters, effectively making their victims' blood boil until they would explode in a weird and supposedly harrowingly painful manner, disintegrating nearby troops. On top of that, Dark Eldars could hover over everything with ubiquitous grace and speed. Their armor was weak, so you'd have to take aggressive action to win.

Dark Eldars were the choice of the pure strategist.
