First off "get educated before you speak", lol that statement though... Next up there must be a reason they did it for scatter grenades too, as such one can presume there is a possible cheese for that too. Then i shall add that i do not play sunslinger, or warlock anymore for that matter, however i do know you can throw two grenades, but can you get two kills as the cooldown only kicks off on kill, not hit. Its all about balance, in balance should you be getting half your super every 10 seconds? No you shouldnt, so its a good thing they stopped that too. At the end of the day the cooldown is fair, deal with it.
