Hmm having taken some of the advice on board I have redone my list partially. I am not super-fussed about it being super-competitive, just dont want to shell on something I will rarely get use out of

I am also happier about the size in points fo the formations being a little lower and more spread out.

Now for the last 250, I was thinking of maybe another Storm Serpent (tho having three is a bit over kill ish

), or a Vampire Raider. Although I am worried that I lack decent long ranged anti-tank, and am unsure whether one set of nightwings will be sufficient. I know the IG player in my group likes his titans and aircraft, so a Cobra or Scorpion might be useful!
I think this is one of the best things about Epic, and Eldar in particular, the tactical decisions that it forces you to make, as well as having a grand plan for how you want the army to work.
