I've been thinking about what class I would choose when/if this becomes available in EQ. My first thoughts were to try a class that I have never played before, but then had second thoughts. A clueless 85? That would be me in some classes. I have never played a Monk, Bard, Druid or Berserker. Could I create an 85 version, then a new version to run through early levels to learn the class. Not a good idea realistically, as where would one stop the lower version. You certainly wouldn't have learned the 85 game.
Create a class you are familiar with? What's the point? I would find it boring. So what to do? In another thread, I mentioned I have several 65 raid gear equipped toons. I think in the end I will level these and thus will have learned the class at the appropriate levels.
