What I propose is that we make a list of the "Iconics" from throughout D&D history. However, for the purposes of this particular list, I think we should exclude characters who actually belonged to certain people (Evard, Otiluke, Robilar, et al.) and characters who were primarily novel based (Driz'zt, Bruenor, the Heroes of the Lance, et al.).
I disagree with this. In my view, the iconics of 1E were the original Greyhawk characters of Gygax's campaigns. The iconics of 2E were the characters from the major novels (Raistlin, Drizzt, etc).
I think ignoring these two sources ignores a huge number of characters that really formed the archetypes of D&D characters.
