Calpheon Ball 2022 :

All the bosses are designed to be solo-able, but Pearl Abyss has gained experience while developing Atoraxxion, and these new bosses can also be defeated in co-op with your guild. The guild versions of the bosses have different attack patterns and mechanics from the solo version.

Please don't lock the new region's group activity to guilds...
Players ask for group activities to be done by 2/3 people and which are profitable
not a guild bosses..

land of morning light bosses will be guild bosses cool or world bosses? i dont want to fight by myself rather do it with the guild or form a platoon

the first part of the statement is "All the bosses are designed to be solo-able" btw...
