Warrior Tanks. Deep Wounds. Why.

This is probably going to turn into a huge rant post on my part, but ill try to be as constructive as possible.

Ive been seeing the hate flying about with the talk of the DW Nerf (Protip: It hasn't happened yet, calm down.) More-so, I see a lot of tanks complaining about this change.

I have never used a DW spec, have never considered it, and haven't really changed the spec I'm currently using. A lot of people look at my build, and wonder why I'm specced this way, and wonder why I'm using Revenge, Heroic Strike, and Blocking glyphs. Ive been kicked out of raids for 'a bad spec', but yet I can easily seem to out-threat, and sustain threat over Guild MTs, when I myself am one, but I have no issue not being.

My question boils down to this. WHY are you using DW? Are you using it because of TPS issues? The extra damage? The Added benefit of a little more AoE Threat? I'm honestly confused that I have no issues holding the threat that I do (AoE or Non) without being 'Properly Specced'. Am I just missing something? Whats going on here?

Feel free to ask me / criticize me as much as you want, I'm just looking for some answers from some Experienced Tanks, preferably not on Level 1 Alt Trolls.
