I think MMORPG have so much safe space lack of competition that it's sterile and boring. Doesn't have to be just trolling and killing.
We play online with 1000s and literally have no effect on the person next to you good or bad. I think that's a sad thing.
I can't remember the last time I healed or been healed by a stranger. Rescued from PvE or even PvP encounter. Got a buff that made a difference from a random. Traded an item with someone. Those were the things that made MMORPG cool to me. The random chaos bring people into the equation.
All focus is on the game/combat side of things. It makes every game feel formulated because no matter how you change combat you are still doing the same things.
