Which in my opinion goes back to the source. People think they should be able to quickly and efficiently complete what they want and have no restrictions to whatever they want. I blame Blizzard over the years for allowing this mentality to seep into the genre, but it's also what got them to 12 million players at one point. Genie's out of the bottle and the genre is going to suffer for it.
If you took the MoP model and put it in Classic or BC, players would see it as they will take longer to get there, but they'll get there eventually. Now some will complain it's slow and inefficient. :/
