From my experience and seeing how people react every time some big thing is added, it's less about people being mad how long it takes to get one and more mad how long it will take them to get 5.

The reality of hardcore mmorpg players is if you make the game easier they will just increase the scope of their goals and then create a massive workload when some new thing is added, and then have to do it x5.

However I feel there are still some unknown factors here, such as was the case with ML where they added higher level monsters.
