OP, ignore people telling you how to play.
PLAY WHAT YOU ENJOY THE MOST AND YOU WILL PLAY THE GAME THE BEST YOU CAN WITH THAT WAY.
A loyal player who stays is more valuable then a player who can pull higher numbers and leaves the moment he is bored or got his loot.
- If you want to dps as a druid Feral/boomie "JUST DU ET!"
- If you want to dps as a shadow priest "JUST DU ET!"
- If you want to dps as a arcane priest and bring extra utility “JUST DU ET!” <–this is me
- If you want to Heal as a druid or priest "JUST DU ET!"
- If you want to be a meta slave warlock dps "JUST DU ET!"
- If you want to to to play affliction because of debuff changes "JUST DU ET!"
all of these bring something to the raid and are viable to raid with. naysayers are just telling you how they think all players need to play or else they need to be banned for not following their guidelines.
