It wouldn't be terrible.
It would be still be fun for me, and I'd still play, but I know I'd get pretty tired of "donating" my entry fees to the advanced players in my area until I can compete with them a little more regularly instead of just when I'm having a really good day. I also see rec players not being as likely to play if they have to pay the same fee as the adv/int crowd. I think it would still work best if adv/int were combined into a single group and rec still had they're own division. I like what they have now though. True, baggers can be an issue, but those baggers would still be in the beating the same people if it was combined, so I don't see any real benefit other than people in the rec/int divisions not having anywhere near as good of chance to win anything.
