DKP 2.0 i.e. EP/GP

The math behind it is crazy elegant.
Basically, having a gigantic DKP pool doesn't mean you win everything, but it does mean you get the lion's share. As soon as lower members get a bone, you're back on top immediately. The more you show up, the less decay affects you (rewarding attendance). While decay also discourages hoarding, if you don't have anything worth spending it on no worries. You will never be passed in priority as long as you have good attendance. Ensuring hardcore raiders can still get what they most desire (just not the next 10 of those things).
