Can't say that I agree. If [MENTION=42582]pemerton[/MENTION] had named his order of Wizards something like "Wizards of the Celestial Towers", and then explained all of their characteristics, I still would have arrived at "Oh, like the Wizards of High Sorcery, but on Greyhawk", but with a lot of wasted discussion.
Whereas with a different name and some changed defining characteristics, I would eventually discover that they are similar, but different, which would still not be all that great as far as I'm concerned, but much better than keeping the same name. With the same name there is no discovery period as the name instantly evokes the Krynn wizards and all of their characteristics, then that image gets broken again as he introduces changes.
