A couple weeks back I talked about how you can pick two combat roles at once in my MMO, and switch them out in town. A comment from David Grundy:

Calculating the Price of Tedium

Of course, I wouldn’t let that happen. I’ve seen firsthand how damaging it is to let tedium be the limiter of your game design. So instead, I’d homogenize and simplify my skill designs, watering down each one so that you could switch classes constantly and it wouldn’t mean as much.

And I’ve Got Nothing Against Pointless Mechanics

Going back to David’s earlier question, do I want to create an “un-fun, time-consuming and ultimately pointless mechanic?”… well, even though this mechanic isn’t pointless, I do have a lot of other pointless mechanics in the game. (Even more so than a typical MMO.)
