KMST 1.2.411 - Phantom

LHC had a city? Weird.

I guess you're ignoring Past Leafre and Ellin Forest's expansion based on technicalities.
Though, to be honest, I'm not so sure what's exciting about new grinding areas anyway since they don't actually offer any new play style like party quests and the like tend to do.

LHC basically WAS a city. Well, a castle, but a castle is as good as a city. Lots of quests, new mobs, a story, and even its own boss. Impossible to not include it. I have no idea what Past Leafre includes, I must have missed it. Feels like something I would've seen if it was extensive at all. Going to look it up and then edit this.

Edit: Okay, had no idea that existed. That's huge. Ellin definitely doesn't count because it's like 2 new monsters.
