See, you prove yourself wrong. Not everyone can go AFK. There needs to be at least 5 or so people doing mechanics. Mostly Tanks and Healers.
Someone has to do stuff. That’s me and you, guy.
I think of LFR like an easier version of Normal, with 20 Dummy Players who might as well be NPCs, and maybe a couple people who might actually help. That’s just the way you have to go into LFR.
