No more legendary questlines or artifact weapons, no more side crap like garrisons, shipyards, or class order halls. Just go back to jumping into heroics, getting the right ilvl to jump into raids, and then raiding.
I am so tired of having to repeatedly do multiple difficulties of the same raid over and over again just to finish a questline or get gear so I can FINALLY do the same raid on the highest difficulty. It burns me out so much that I just don't even want to bother anymore. It also completely punishes people who ever quit and want to then return to the game, but are met with an awful catch up instead of jumping into content more quickly.
I love raiding and it's still very much fun, but the process of getting there is absolutely terrible and boring right now and I'm not surprised a lot of people are just like "why bother" instead. If it's not better in Legion, which judging by what I've seen isn't looking good, I think this is it for me. There are seriously grindy Korean MMOs out there with a less time consuming and less boring process to step into end game at this point.
