Heroes with Low-Cooldown Ultimates

This post started out as "teamfight ultimates", but the spirit of this post includes heroes that can fight frequently, and thus includes more single-target ultimates, and heroes in general with low-cooldown abilities.

At the time of this writing, heroes such as Slardar, Tusk, and Witch Doctor are popular in the Pro scene, somewhat because they don't have to wait on the cooldown of long ultimates to fight.
