Grenade launcher should be direct target instead of ground

I find that the Grenade Launcher's practicality is that you get perfect placement of the grenade at distance instantly, and that placement is often centered somewhere other than perfectly on a target when in a moving melee. (For example, placing a concussive so it doesn't hit your allied melee, but does hit the three people they are fighting)
Snap-to-target *in addition* to ground target might be useful, but unless you are queuing a launcher after an auto-attack or some other ability usage, there really isn't any time for the mob to move.
