It's so funny to see people cry about this when Rage/Focus has been able to do that damage since......ever.
It didn't always have the armor penetration, and it didn't used to be so easy to land. However, if you must know I've always had an issue with smash spec just for the sheer fact of having such a high damage ability be an AoE. However, before it could be evaded, not so much now. It is literally a low risk high reward spec. The top dps in a warzone now are always smash specced players, ALWAYS. It's not even close.
