why not go with 1 block diff change ? it is working very well on at least 5 coins and it totally stops the coin choose affect and makes it fair for everyone

This time it was not decided by me, it was open for discussion and that is what was settled on.
I am going to be doing some major work on the QT client, time frame is a couple of months, so we'll see how this change works and go from there.
