The fact that there is so much pressure at the one event to keep everything working, patching things up, the getting it back together again before your next fight. That is part of the challenge and (for me anyway) just as much a part of the competition.

The idea I do like is a ranking system based upon results over a number of events but, as LJ says, it may not be possible for everyone eligible to be able to attend all the events where rankings are at stake.
