I prefer 1 % of block rewards being channeled to the developers. Last time I calculated the daily mining rewards it was 7700 XMR so 1 % represents 77 XMR which should be more than enough with the current prices. Even smaller percentage might be enough especially if the price grows in the future.
I agree with the numbers, but that change is evasive and would change the social contract, so not a good idea, I am totaly pro a transaction fee, and I will support it
