I'm perfectly fine with the format used this year. On courses that are set up to provide proper challenge to Gold level players (which has never been a reality before this year), four rounds should be more than adequate to determine the best player in such a deep field.
BUT...in the interest of blending the new with the old, I could get behind a 5-round Worlds. That being four rounds like they are playing now with a cut to a Final round of 18 for the top 54 or 72 (or whatever the cash line might be). I don't think it would do all that much to provide more drama or closer battles, but it would set the event apart from the "regular" tour events of the NT/DGPT/DGWT/A-tier schedules and bridge the gap to the past format somewhat.
