So it seems that fast hitting weapon don't make hydra hit higher. What other skills are affected by attack speed?

For example, in general, I presume that higher attack speed don't increase damage per attack but increase dps. 

However, for skills like hydra, or earthquake, where the cooldown is the limiting factor anyway, it doesn't seem balanced to not taking into account attack speed.

So how does blizzard sort his out?
