That is a nice next step.
100,000 per proposal isn't unreasonable. Personally I would like to see it changed to 10,000/25,000 DEC to submit a potential proposal + 100,000 DEC listing charge if a said proposal passes the first step. For a charge of 10,000/25,000 DEC if a proposal doesn't get listed on the Splinterlands site or a charge of 110,00 or 125,000 DEC for the ones that do.
100K DEC should be a bare minimum. I actually think it's too little to be honest. 200K DEC sounds right. The less proposals the better. Too many proposals passing will take up more developer time.
I agree with your initial statement but currently the 100K isn't for an official proposal. Its for the opportunity to suggest a proposal. The suggestion needs to pass in order to become official . With that in mind 10/25K for the opportunity to suggest a proposal and additional 100K* to officially list it seems reasonable to me. However I understand the time restraints might be unreasonable to let too many suggestions get in so cutting back on the amount of suggested proposals needs to be considered.
With further thought, I agree with this. I will vote for it if it comes up for proposal.
