Ignore what anyone says about how good certain tanks or healers are at certain roles. Top guilds may not use Resto for tank healing when pushing Mythics in the first week or two, but for anyone else they are perfectly fine. We can always switch around who plays where though.
I'm going to end up working evenings for some time from November onwards, so starting to gear for Mistweaver so we can have another tank take my place. I will still be tanking Mythics and such, and will happily tank raids just don't want people to be fucked because I can't make a raid.
