I personally don't care if magi has a gpuminer or not (but I have been contacted by someone who had your authorisation to make one. for amd, it isn't like nobody is looking ), what I don't like is that you want to change the rules of the game middle game. And technically it will just hurt the small miner. People with large hashrate will still have large hashrate but since the decrease of the hashrate they will clearly make a lot more with your reward system. So actually by changing your algo you are even changing the "fair" distribution and reward system you put in place and sorry this seems fishy to me...
