Hero abilities

[Katarak]

First of all i will hold me short. After the update with the boss abilities come out i had the idea that it would be really nice to get abilities on a hero char. This abilities should be usable more than one time, maybe after using a cooldown of 1min. For example legi get for 10 sec 3x one handed speed or warden can shot 5 times 3 arrows with one shot.
