- Mike Mearls goes without saying.
- Sean K. Reynolds would also be a must.
Um... that's all I can think of.
Part of me would reccomend Steve Kenson as well, but I think we can assume that he has not been living and breathing D&D the way some other desigenrs have. For this reason I am a bit hesitant, even though I'm confident he's one of the top d20 desigenrs around.
Most importantly, I'd really like to see WotC
hire a team of dedicated, hardcore playtesters; I think ENWorld would be a great source. I'd love to see peeps like John Cooper, Psion, Hong Ooi, and Priatecat just hammering on prototype D&D rules 40 hours a week, with their opinions weighted just a wee bit heavier than the rest of the hopefully massive amount of regular-Joe playtesters.
It would then be great to see someone like S. John Ross get invovled with layout and formatting. I'd also love to see some professional information designers look at ways to make the rulebooks into powerful
tools that aid gameplay. A team of editors to pare down the prose to maximum brevity and clarity would be nice, too. Then, a team of proofreaders (maybe headed by John Cooper) would pour over the final text for months making sure it was error-free.
But I guess we're firmly in the realm of pipe-dreams at this point.
IMO, 3.5 is in little need of revision. However, I do think that some sharp minds (a la Mearls) could make the rules clearer, more useable, more readable, and more
fun without making any drastic changes. I don't need a revision, but I do want to see 3.5 made
even better.
