Eureka sounds really neat but I kinda have a bad experience with it still. My boyfriend would run Eureka for a whole month the last month of summer vacation and I couldn't talk to him at all because it's instanced and he always had discord on do not disturb because he didn't like the ping sound.

This was like, right before my last year of uni and I really wanted to spend the time with him. But I was in heavensward and early stormblood and I just, couldn't even talk to him. It hurt.
