Hello everyone, so I've been playing Destruction for a while since I've hit 80 but today I got Dual Spec and want to go Demonology. I was wondering which glyphs I should get and how do I play at raids, and what talents should I get? Some people I inspect have Felguard and some don't, I'm not sure which way is better. Also if Demonlogists does not use Felguards, which demon do they use? Thanks in advance.
