Actually I had different plans but that got stomped by the ScrollFrame finding.
So I'm currently in the process of rewriting the orbs for oUF_Diablo in adaption to DiscoKugel2.

Hopefully things will work out properly. I ripped apart huge parts of the config.
I'm currently testing orb values on mouseover. Added on optional switch for that. It can be OK for some classes not to know the exact values all the time. For my warrior that just doesn't work out because I have to pool rage and need to know the values at any time.
