If You Were A Class/Job Designer...

[Shurrikhan]

Can't think outside the box if the devs basically want jobs to be contained in 3 different boxes.

This, honestly. Presently a tank is (1) higher (m)Defense, (2) % mitigation CDs, (3) enmity-modded skills, and (4) a tank stance, with a less crucial side of resource and resource builders (mana/stacks), and where GLD is leveled to 22 or higher. The goal could be accomplished in far more ways than just an arsenal of CDs (Inner Beast, etc.), and yet I pretty well doubt this fairly exact design will change without some underlying changes in design philosophy across the game.
