Fear not! (no pun intended)

You have the 2 min trinket which is the same cooldown as WoTF

And....!!!

In an upcoming patch all Mages will be receiving Ice Block as trainable, which basically you can use to sit through the barrage of anything. 10 seconds to get your barrings on anything.

So there is still hope, don't feel bad

I played 3 Mages for almost 2 years with only a 5 min cooldown trinket, I know the pain.
