1. How do you think your Assassin spec is perceived by other classes?

In it's current form, deception is viewed as a joke spec. It simply does not have enough burst/sustained DPS to be viable. People would rather take a tank/ madness assassin into endgame content because they can do my job better.

2. How do you perceive your own spec?

Deception is one of the most fun playstyles and one of the trickier AC to make perform well. It can shine under the right circumstances but, in endgame content, those circumstances are few and far between.
I personally would like to see something done of the damage/force re gen side of the deception builds. it's fine to be a glass cannon but not when the cannon isn't big enough or can't be fired long enough to be effective.
