My biggest fear is that Warriors will be forced to 'stand in fire' in raids in order to keep their enrage proc'd.
Druids had to do that in TBC and it wasn't fun until it was changed.

I had the same worry until I realized that Single Minded fury will increase that damage by another 20%. It probably still wont hit as hard as TG, but I'm sure they'll make up for it in other areas.
