What I hate most about it, and a discouraging number of other systems, is how they override a player’s ability to decide when they’re ready to approach content.
I think it was day two or three of the expansion that we were in heroic Shrine at 258 ilvl learning everything the hard way, but having fun doing it. We could do it because beyond leveling up and going to the dungeon, there was no system forcing us to jump through hoops to unlock it . We decided when we were ready, not Blizzard.
I think time-gating has been overused and has become really, really tiresome.
