[a bit of an odd fish]

If you really don't feel like painting any more eldar for a while, then i don't think dark ELDAR would be wise. Their playing styales are quite different, but basically the same. Going orky would be about as different as you could go, as far as painting, models and style go. When I collect two armies, I like them to be pretty different.. but whatever you want to do.. wanadoo broadband.. sorry ignore that last part. Anyway if you want to play DE then speed is your armour man
