True MCs are supposed to be better then most things. But some Armies don't get any. And most of those that don't get MCs get some kind of Close Combat Walker, aka Kans, Deff Dreads, and Dreadnoughts. I just think it's unfair that they get torn to shreds by MCs...They're called Monstrous Creatures, they're supposed to be better than most things on the tabletop, the way they are now is great except for the MCvsMC case which I agree with letting MC get a save when hit by othe MCs..
However in fluff, art work, and video games we see MCs going toe to toe with these kinds of Walkers. I think there has to be something they can do to make it a bit more of an even fight.
