I'd only half agree with you.
I do agree that we don't want to reintroduce the exact system we removed, with all it's problems.
But I don't agree that the proposal needs to have all specifics completely sorted - this represents a stake-weighted poll, to determine if the community wants to give the team and DAO a mandate -- to work together and come up with a workable league-type system.
If this passes, it means we need a working group to explore the old problems and propose solutions. I'd suggest as a gameplay issue, this is totally under the team's purview, so this type of open-ended, detail-lite proposal gives us the ability to find out what the stakeholders want as a whole.
