If you feel that they've been attacking you, shouldn't you report their posts? Aside from that, I do share your opinion about the narrative-changing powers of spellcasters. I do suspect that it ultimately boils down to Gary Gygax himself, who did play a lot of powerful magic users himself, with Mordenkainen being the most prominent example, who did have such stuff like an impenetrable luxurious mansion that has a 1st-class service, a magical sword that can attack on its own, a super-dispel spell that can dispel everything, and other stuff... basically, he's the very first Dungeon-Master-Player-Character... created by the first GM, Gary Gygax himself... who also made his DMPC the most important guy amongst the greyhawkian justice league... and the reason Robilar, the dumb fighter, was even worth mentioning is that Rob Kuntz had solo-sessions with Gary Gygax and could level up his character fast enough to overshadow the other "regular" players...
