Here is an unintended problem with the DKP decay, and this is what triggered the controversy.
Person A has been raiding with the guild since day 1. Rarely misses a raid and has made some purchases along the way.
Person B comes in the guild 6 months after DKP has started. Rarely misses a raid, has made 1 purchase long the way.
Because person A has been in from the beginning, he is actually earning less DKP week to week since he is affected by decay on DKP earned prior to person B entering the guild. This in turn causes person A to want to horde their points since Person B passes them up in current DKP balance. This is the complete opposite of what, I believe, was intended since this actually punishes people that raid consistantly for extended periods of time.
