4.1: RDM's Dualcast can no longer be clicked off.

[Elkanah]

That triggers your gcd and costs 2.5 of your precast time.

You shouldnt need to be using anything involving dual cast before a pull.

In dungeons, use veracure on yourself to get rid of it.
On raids, dont use it pre pull.

The question is why do you have dual cast on before a dungeon/raid boss pull?

Is it on? -> veracure to get rid of it
Why is it on? -> I used it on something -> veracure to get rid of it.
