2000 points against Eldar/Tau

Hey DarkCity,

haven't posted in a while, but I've got a list question for you all. I'm playing 2000 points against a pair of 1000 point players who are either Eldar or Tau (or a combination) and I'd really love to smash them hard. This list is set up to hopefully deal with wraiths, Riptides and serpent spam alike.

C & C not just welcome, but needed.

Thanks for reading!

So I came here a week and a half ago with a Character Heavy Dark Eldar list tailored for Tau and Eldar opponents, but that got carved up, so here's my re try.

What would you change? What would you keep the same? What are your concerns?
