Why do you think nothing in the game should take more than your 30min's of play time to do, you have access to everything, nobody stopped casuals from doing Ein/Salvage/ZNM's in 11, though few did. HNM's are there, ive seen KB/faf/nid walking around tones of times, some servers like mine had HNM's before i got into it and the major HNM ls's basically destroyed eachother which lead to HNM walking around for years only being killed maby once a month.

The access is there, casuals would simply rather waste time.
