The thing I dislike about MMORPGs is that they always have the same problem, and its always because the game is an MMORPG:
The whole game feels like an amusement park.
The scale of buildings and hallways is always comical. I always have to wait in line for a dungeon/raid/boss/NPC, etc. NPCs always feel like theyre there for a photo op and everyone is always crowding around them.
I wish that MMORPGs could add a feature where I can play in my own "channel," where the only other players that appear on my screen are ones I have invited to my channel. Because some MMORPGs are appealing to me, its just I don't like the crowds of ten trillion people all doing the same task "only a hero can do."
