Thanks for sharing your thoughts in here, this is a good read.
As others may have already pointed out, Arbitrum DAO is finishing a review of the previous incentives programs, exactly to act upon some of the findings you highlighted here. Your suggestions are a good extra material for the discussion.
I invite you to add more data into your analysis, building upon the extensive research being conducted, as the one I’m pasting in here.
All in all, the time is ripe for we, as DAO, to lay the foundations of a new incentives program.
