LB in Arena (Melee Gripe)

So, I know getting to LB stages are rare and stuff but... Melee LB really, really, really sucks in Arena. Getting someone to stand still for 3s is extremely unrealistic, not to mention, since the game has gone on that long - stuns are on DR, etc.

Is it possible we can shorten the cast time on Melee LB?

It's literally an instant kill.

Coordinating a stun/bind/sleep/something to keep them stationary is fine, honestly. :l

Imagine being a caster and LBing... 100% wasted if they move out of it. At least as melee it cancels the effect and doesn't drain the bar :P
