Yeah, I've always liked to be an execute monster.
It is our main strength and sole reason why shadow always was and will be one of the best specs for progression raiding.
Also, ToF is one of the coolest talents in the game and if you think it's boring, you probably not really good.
The main issue with shadow right now is that our talents are total crap. Couple of rows need complete redesign, some should be deleted and replaced.
