Even while creative maestro Metzen experiments with making World of Warcraft unique among its fantasy peers, there's not much denying that WoW has some pretty solid roots in, and respect for, Dungeons and Dragons. You can see proof of that in the patch notes from 2.4, which were dedicated to pen-and-paper legend, Gary Gygax. Many of us cruising Azeroth have some experience with good old D&D. WoW has pretty strong, deep roots in D&D, and those roots changed with the newly released 4th edition.
What's new in the 4th Edition Dungeons and Dragons? The class system is radically different, spells work differently, healing works differently, and fights work differently. Okay, it seems everything is pretty much different. But there's one big change that will probably make more than a few folks happy: no more Gnome PCs. Gnomes are now monsters, and not available for play in the core rules. A lot of the speculation about these changes is that D&D might be trying to distance itself a little from the World of Warcraft juggernaut.
It's a good thing Blizzard isn't still following its roots. I'm looking forward to my Gnomish Death Knight in Wrath of the Lich King.
