divide true born into 2 squad and give them more special weapons. warriors squads are good for holding objectives, and pretty much it, if you give them a DL then drop the raider as it just add free KP. other mobile warrior squad could be wyches instead, add more of a cc punch, or even blood brides. Also too many reaver imo, take 3 to 4, boost and shoot heat lance in enemy tank's rear and their role is done, too much expectation on them will only bring let down.
That's pretty much it for general opinion, other changes can be made but depends on what you want, there is no crappy list, so if you feel happy enough that's all it matters.
