Balance, Homogenisation and Encounter Design: The Problem.

[linay]

Wow, so are we really down to cosmetics and pushing buttons in a slightly different order?

In my opinion, as it should be. A job is not just a job. It has a role and role identity trumps job identity. A dark knight should be a tank first and foremost in its identity and utility in a fight while offering the identity of a dark knight in terms of aesthetic and lore and flavor text and maybe order of rotation.
