Massive city battles with invading forces.
Ferry/Raft rides with random events.
Meaningful exploration with difficult mobs, mazes, unique pathways, and things to discover.
Skill-based battles rather than combo-spam.

Eureka is literally just 100s of people running from nm to nm killing things near instantly, and lagging people out. It's basically just hunts in a special zone with pointless mechanics everyone is ignoring.

And rather than make the zone interesting, it's just groups of mobs scattered in giant areas with almost nothing interesting to discover.

I don't understand why devs keep implementing the same 100+ person spam hunt/nm/fate mechanics, that lag people to death, and make the monster your killing disappear from your screen due to the number of people.
