I made little videos like this on my warrior during DS and people liked them. Even though I am still somewhat newer to shadow priesting, I thought I'd share some of the key things I've learned so far, as well as show my weak auras with exports. I uploaded it in 1080p in case you want make it big.
I managed to pull about 50K dps unbuffed, but I would argue Halo hitting all the dummies helped out a bit Either way, I've ranked top 100 on a few mogu raids so far so I figure I must be some things right. Feel free to correct me or ask questions
