Only thing you can do is revert back to Yosemite or wait it out and hope it works in the next beta build. That is the risks of installing beta, some things might not work on any given build.
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.
