I guess this sort of begs the question as to whether or not any of the magic "pros" are professional in the true sense of the word. As such my question could be better re-rephrased as "does vintage have something analagous to the pros that constructed formats have?" Of course, that's a bit long for a thread title.
In terms of the publicity and attention that certain players get, they do parallel the "pros". Then again, the effect their opinions have on the metagame are nowhere near the complete reversals Kai's publications effected. Part of this is due to the inherent difference between formats. Someone could come into type 2 more or less cold and just pick up whatever Kai was touting (say UG Madness) and play it in a tourney for under $100. When Smmenen says that Oath with eight power and drains is really good, people are more likely to play to beat it, but most won't take out a loan for it. Of course, here on the Drain, Steve is lowered from emminence by engaging in more interactive discussion, which "pros" would not participate in.
As far as whether or not we are better off not having pros, I don't know that that is necessarily true. We are certainly different and unique.
