Actually, I think old definition Smackdown characters are kind of expected. 200 points of damage isn't exactly all that tough by level 15. Is a rogue that uses 2 weapon fighting, haste, and expert tactician really all that abusive? If a wizard throws 3 good attack spells, is that an exploit? Not really. It's only the ones that greatly exceed 300 and can be used all the time that worry me. Some of the psion Body fuel ones are amusing, because the character has crippled himself to do it.
BTW, I was wandering on what people think of using the metagame knowledge in this thread to influence combat actions. For example, I imagine many people could find a use for a Disentegrate spell, which is apparently in reapersaurus's Ioun Stone.
And I think my character might have done passably well against reaper's original monstrousity. It probably would have been incredibly boring for awhile, though.
