But the eldar are such goddamn pussies outside of their ultra heavy gear.

After playing with orks for a while, I agree that they sux0r. It's not that their units are all that bad, but they've got a weird resource system (you need X amount population to build building Y, eg) and are just too weak at the beginning and lack proper defensive buildings. But they do have that HUUUGE animal dinosaur monster, Squiggoth or such. Neato.
Oh and I summoned the demon thing with Chaos. That thing can wipe a base on its own! Pure pwnage. Although coolest unit in game remains the dreadnought, yeah.
