I just want an open world repeatable multiplayer content.

A map or planet that the map is a giant event.

Multiple mini-events happening all over the place, since we have shared tagging there's no need to join groups.

Mobs HP would scale to the number of players around. 

After completing a certain number of events, the final boss spawns, players gather together to kill it.  Give it good rewards and people will grind it all day long. 

 

I miss the "massive" part of this MMO so much. 

I spent 2 hours helping people with the heroic on the Rakghoul event, it was super fun interacting with people in the open world.

Depending on how it's designed PvE might work, but they already tried PvP on Ilum and the game engine couldn't handle it. The game became a slideshow even on the fastest computer. The SWTOR engine scales really badly with lots of players in one spot. You can see this with world bosses during feast of prosperity when 50-80 players are in one spot fighting the same world boss. The game slows way down. For PvE, it might work if they have multiple equally rewarding activities occurring at the same time to spread players out. Otherwise, it's not going to be a fun experience.

GW2 has what you are looking for.
