Magic Missile cooldown is too quick?

[Ali0en]

I'm not sure if it's been changed lately, but magic missile comes off of cooldown very quickly now. Basically, any wiz will pick fireball and abuse it with MM. So just teleport in, cast MM, target is stunned, cast fireball, target is unconcious, MM is off cooldown, repeat. We had a wiz today take down 6 people in surgery by stunlocking with this. It's coming off cooldown far too quickly and the combo is just too good.

I understand the wizard is one guy against the crew (when it's only 1 wizard) but come on. This stunlocking is insane.
