First is about a bug(maybe)

The skill of wizard "hydra" and "blizzard" never cause critical hit
Even I have 19.5% critical rate, I never see these two skill have "yellow damage number" on monsters.
I think this could be a bug, so I post here to official and hope that will be fixed.

Skill discussion

I do not know where to ask or give some advice
These three wizard classical skill have a big problem
I think the attack speed doing nothing to "hydra", "blizzard", and "meteorite" is a huge penalty for wizard because in Diablo 3 the attack speed is too important.
There are too many wizard skills can not be supported by attack speed and even critical rate.
I want to know the opinion of the wizard skill designer.
