you got 16 slots - you need on average 2.5 dungeons to get an item
thats 40 dungeons at like probably 45 minutes each if you consider traveling and all that if you do it back to back = thats 30 HOURS minimum not accounting for ilvl, duplicates, rating farming, specific items or tyr/fort having to be run seperately to get into groups
i dont think M+ is too rewarding for anyone that doesnt literally breathe this stuff, not even thinking about like 1/3rd of the runs that get aborted
how is it a problem that somebody who puts obscene amounts of time into the game gets more out of it? you could make the same argument for gathering making too much money
