Critical hit and damage bonus for special attacks

[Nevar]

So far, I have yet to see a Rage skill critical. Icy Rage is buggy. The freezing effect only works for Olaf's non-Valkyrie skills and I've NEVER seen a Rage skill crit.

Some special attacks DO crit now, mostly the ones that are more powerful versions of basic attacks. I can't comment on the second question, as I frequently run without those, since I mostly use high-level units, who benefit less from them.
