TBH Memespecs should only be taken to raids when they’re on farm/pug status. If you want a spot in top raiding guilds, you gotta play the meta.
For instance, I want to go Shadow/Holy spec. But I know my only utility in a raid if I do that is my shadoweaving to give locks a DPS boost.
So I’m going full holy/disc once I hit 60 so I can do raid content without having to fight for the ONE shadowspec spot that many raids don’t even have open yet.
