We have been using our fixed cost standard DKP system since our guild started raiding about a year ago. There is some inflation, as we anticipated when we started using it. A typical night of raiding earns a player about 8-10 DKP and we have been raiding once or twice a week depending on attendance. Our most experienced raiders have accumulated over 100 DKP, so they are well ahead of where a new player starts out, but not outrageously so.
We are deciding now if we should reset DKP for WotLK. We won’t be raiding until we get to level 80, anyway so the DKP won’t be used for a while. It feels like a good time to reset. In fact, it feels like a good time to completely revisit our DKP system. But some people are a little upset at the prospect of losing all the DKP they have accumulated.
