I played a much older version of this before and it was cool, ive just come back to dawn of war and played your latest one and wow man, good stuff.
Ive been playing the campaign using this mod and its a lot of fun, i like that units reinforce faster when they are not in combat (at least thats what the rule appears to be).
And i love the speed at which things die, i hate seeing units take 50 million bullets before they go down.
the only problems ive had with it are ones that i dont think you can do anything about (ie pathfinding).
oh wait there was one thing - sometimes units forgot their command list (shift - clicking). but meh.
edit: my vote - 2 aswell. Perhaps you could increase the griffons range but decrease damage? it is really short ranged atm
