Because that was sooo much fun trying to coordinate a full party mixed with E, D and F players! Actually, I'm with you on the harder content, but not if its in a daily roulette crammed full of easier stuff (like the trial roulette). People still leave steps of faith as it is, and very few people select join in progress because of it too.
Also with you on the AFKers, which I loathe every since my WoW LFR days. Funnily enough, most of the AFKer back then were endgame raiders that saw the content as beneath them, and would rather autoattack while watching something else.
