Same sight on this for me, as I’m also coming from RO.
Orc Dungeon in RO was always filled with Homunculus-AFK-farming Alchemists/Genetics, and also fine for Looters to make Zeny. Actually healthy for the entire game. A few adjustments for ToS regarding Quests and alternative active playing/grinding maps, no autoloot for AFKers, and it will be a harmless alternative for some players. Also fun for other players (not so much for the AFKers) to occasionally fire off a bloody branch to spawn MVPs (bosses) who wreak havoc there for a few hours - all the dead Alchemists/Genetics littering the ground, haha^^ And I never fired a BB there, i was on the receiving end, but still funny thinking back.
It’s right there on their website
