Alright I'm not trying to bash you're list or anything but as a chaos player this list doesn't scare me in the least. Here is why. Fire Dragons need to get a tad to close to marines in order to kill and that makes the counter charge much easier.
What I would do is round up the Avenger squads to a full 10. Lose most of the Dragons and take some Banshee's in a wave serpent, a Wraithlord, Fire Prism or Reapers.
Another way to build the army is with a bunch of Jetbikes, Vypers and Warp Spiders. Marines can't keep up with Eldar use that to you're advantage.
One last thing is Marines HATE Starcannons, so take a good amount of them.
I hope this helps some.:biggrin:
