Just an FYI:
When Divine Purpose (DP) procs, I can cast Word of Glory (WOG) over and over again, for about 15 seconds. For some reason, WOG doesn't consume the DP proc. I'm not sure why. If I cast another Holy Power (HP) finisher, like Light of Dawn (LOD), then the DP buff goes away.
I also noticed something else odd - it appears that WOG is consuming more than 3 holy power. It appears to consume 4 HP now.
I didn't see this issue persist with LOD, just WOG.
It seemed to proc a little less yesterday - so I'm not sure. I also posted this on the beta classes forums, where someone said that they were able to proc 30 back to back: http://us.battle.net/wow/en/forum/topic/6079610797
I am more concerned that WOG takes 4 holy power...that needs to be fixed!
