Odd, I'm running WoW in the latest DP (which should be equivalent) with no issues. Out of curiosity, what is it doing?

Also, was this an upgrade from beta 4 or a new install?
 
I can run WoW just fine as well.... I say fine, I do have a few crashes every so often but a restart will usually fix it for a few days. I'm not 100% if this is OS X or add ons but it works.

There have been a few people in the Mac tech support forums for WoW not able to run the game in the latest PB 5. That it crashes even just trying to launch the game. (I haven't tested myself yet though)

It's partially both OS X and the Mac client for WoW. OS X because it's new, in beta and things are different. The WoW Mac client because it's also not updated specifically for El Capitan support yet. It still technically only supports up to 10.10.5.
