Jinx's SMD Rocket has way too low a cooldown

With the 90/75/60s cooldown, you can pretty much throw it out whenever ANYONE gets low, and if you hit, cool, you get a kill! If you don't, who cares, it'll be up soon anyway.

Meanwhile Lucian's ult, which was more useful as a waveclearing tool than for any practical combat application, gets the shit nerfed out of its cooldown.
