But then, I'm an old HERO fan...
Me too, from it's very first release back in 1982.
But for something as potentially diverse as some of these classes, reflavoring should not have been so necessary. Too many good designers at WotC with either experience doing or having played in systems with more flex should have seen the potential from the get go. In DCv1 and Pathfinder, the Sorc class got broadened to what it probably should have been from the get-go. The Warlock had to wait until 4Ed (AFAIK) to get similar justice.
