Well i dont think he is looking for tatics.
I think he is just wondering what other poeple have tried out for there own tatics.
Personally i like my raider army. I was coming up with some new tatic that i thought was pretty cool. It is going to be based on reavers and using them for blocking. Then charge everything up behind them mainly wyches because it is going to be a wycch army. Maby 2 squads of 5 reavers. zoom them 24 ans the raiders behind them. Some qsuads on foot and others in raiders along with warp beasts and a strength 5 powerwepon archite. I will post the army when i am done with it.
