something that would make us play with more people.
A raid? A world boss?
instanced world boss like 20 people.
Oh, that might work too, but boss fights get boring quickly I want a huge dungeon to explore with many people then go to a boss fight. Even without a boss, a dungeon would be more than great and would make the game and especially guilds more active. I'm thinking about one new permanent arcade gate that keeps changing whenever gates change where the levels are much more spacious, maybe like 2-3 times with a lot more monsters. But basically just larger versions of the normal levels. But for boss levels IDK, these in particular might take more time to do than the regular levels.
I'd love to see a superdungeon with a unique type of party button in them that requires players to split into equal amounts on two buttons to activate. This way, you can have two separate parties working together for a common goal, and joining together for specific fights, perhaps fighting enemies from two halves of a separated arenas, and other times working together in a massive fight with a puzzle element to it.
For the actual levels, you can have players on one party side solve a puzzle for the players on the other side to progress, and overall it would bring an essence of required teamwork to complete these levels.
Maybe something that would be called "Ultra Shadow Lair" where a maximum of 8 players can get into. Basically the same as normal shadow lairs only larger and have more monsters, monster health, damage per monster and loot. Cause a world boss would be way too laggy that nobody would even be able to participate xD
