The point limit seems a bit random, I'm guessing you've just added up the models you have and/or like? I suggest working it down to 750 or up to 1000.
Some obvious suggestions:
- Too little anti tank. You've got two Dark Lances and a Heat Lance. Expect the Raiders to wreck/explode early and the Reavers to draw a lot of fire.
- If the Reavers are to be tank hunters, drop the caltrops. If you're shooting, you're not bladevaning, so those points are wasted. You've got plenty of AI with all the splinterfire anyway.
- Give some of the Scourges Haywire Blasters for some long range, shoot jump shoot AT. If you want a cheaper option pointswise, swap a unit of Kabalites for Wyches with Haywire Grenades.
