Thanks all. I've been enjoying going afk, parking the mount very conspicuously at the entrance to Krasus' Landing. Surprisingly I'm getting a lot of people /cheering at me instead of /golfclapping or making derogatory e-peen comments like I expected/wanted.
Looks like they're putting Immortal back on the Ulduar meta but changing it to be on a per boss basis instead of for the entire run at once. Makes it a lot more manageable. I am glad they are also apparently changing the title associated with it though, I like having a unique one for going through the horror that was Naxx Immortal. Yeah, I suppose Immortal will actually still be an easier title to get because of the new gear, but I don't think it will be quite as easy as a lot of people think, bads will still be bads.
