I agree with you on a lot of your points. I like the idea of an extra shot, +1 strength and rending with the cannons, but i hate the price on range and points. I can also see your point with the dread.
Ill work on a new list with the changes, I just have no experiance playing msu, razorspam, ect. So any ideas, tactics, and tips I can get would be apreciated, so I have to ask your logic on my rune priest and the rhino, why have stormcaller with long fangs?
Oh, and the 75 thing with the fangs, its how I write my lists and I was tired when I put it up here and forgot to take that off lol
