I think removing the team requirement will increase the price because new users will need to purchase GRC to help them stake. If they are loyal to a team they would not want to join any of the pools.

I agree with everything you have said except for voting on changes to the DPOR reward system every quarter.

I think the reward rules should be set in stone otherwise we end up like a central bank voting on whether we should print more money or not. And who doesn't want to print more money? Everyone would vote yes and the coin would be worth less than a Zimbabwean dollar.
