Miners keep complaining about the 90%

they give from their devcoins, I think this complain comes out of fear to "lose" their potential wins

, this may sound to some a bit absurd, but please let me know if I am wrong.
Devcoin has enabled Merged Mining, so there are no potential losses since you can also mine Bitcoin, Namecoin, and others at the same time. It would be pretty bad to try to solo mine Devcoin without an ASIC though since the network hashrate is awfully high thanks to Merged Mining.
