Hey Ring, in your current guild can you check to see if my dad is still there? He left for smokes and never came back. More seriously, if you have the receipts for your spec I don’t personally care if you raid as Survival. We have in our guild (They’re playing Monk RN) someone who was top % parsing as survival to prove that it could raid in Legion. Play what you want as long as you are willing to put in the work to make the spec work.
Here’s our post. Give it a read
