True and some subclasses don't without help ie voidwalker, night stalker, striker, and nightstalker. However again with sunsingers their firebolt is in the exact same boat as your smoke. Without those two extra perks it is garbage as a stand-alone. Don't get me wrong I'm not saying it needs nerfed. At least not directly. I feel other than that nightstalkers are balanced and the simplest way to fix that without actually touching its power or abilities is just add a small delay for all classes between throwing a greande then throwing or using a melee.
