As far as I'm aware, no one has more titles in HBD right now than myself. And my ratio isn't too shabby either.
It's from that point that I share my opinion that this thread is really pointless, it indicates literally and absolutely nothing about the quality of the GM's at the top of the list. Just as pointless is counting total titles.
In the end, a jury of your peers is the best form of deciding the top GM's in the game, and to my knowledge none of the guys who's names are always brought up are starting threads touting themselves in the forums.
