The following comment represent the views of @SavvyDAO as I’m part of their team as Governance Analyst:
Thanks for this proposal @Frisson! It’s a great way to boost security and get more people involved in the DAO governance. Redirecting surplus ETH to active ARB holders is a smart move. The use of Karma Scores is interesting, but it could be improve adjusting it to focus on recent activity to avoid concentrating power among older delegates. Adding measures to balance voting power would also be beneficial.
The introduction of liquid staked ARB tokens and a fair cost structure are strong points. Address the concerns about timing and power concentration, and this proposal could significantly strengthen the DAO by keeping things secure and ensuring ongoing participation.
