I noticed CoC got pretty difficult after the last balance changes (elven maneuvers, savage curse, flash of agony getting weaker mainly). Getting far seems to mainly depend on getting at least one priest, preferrably 2 every map. I think especially wizards could use a buff. I'm not advocating to make CoC too easy, but the slightest buff of power for some of the weaker characters wouldn't hurt I guess. You guys probably have the stats on this to see if what I'm saying makes sense.
