I already completed the survey, but got to thinking about something tonight that I thought that I'd post as a kind-of addendum to it.
I am wondering whether a decent approach might be to create a complete, cleaned-up rulebook... and add a section of "optional" or "advanced" rules. These optional rules might include things like customized Mage design, reduction in list of conditions, or whatever you want. That way those who would want to play the game as it currently is simply would not use the additional rules, and others could play in other, equally valid and balanced, company approved, formats.
Each tournament head judge would choose which set of options (if any) to use at a con, but I don't think that that would be a serious issue. It might even be better that way if the community changes its collective mind over time about which set of options it likes best... tournament standards would just change over time with it.
Please don't hate me too much for suggesting this
