I'd feel no pity for anyone who feels that way. I have two other melee jobs at high level, and while the change in play is notable between, say, my DRK and my RDM, I also acknowledge there's a difference in how the classes are designed.
Something I was kicking around that no one seemed to like was the idea of splitting what a RDM could do in the front and in the back. Say, heal and buff while in the back, melee and enfeeble while in the front. I've never been in favor of just having melee mixed with heals/refresh/haste because that creates redundancy while at the same time causing us to lose potential melee time due to casting cycles. It's certainly doable, but not fun and casting-intensive.
