In addition to the individual boss battle, which I like, it would be fun to have all the guild members participate to kill a super boss. Some other games do this like Lords Mobile
Here is a link to this very subject with some really good ideas from alot of players.Some would have kept guilds full and would have required teamwork. What do we get? Another boss pit fight instead. Umalat should require a guild effort just likethe game requires your heroes to work together.
That would be really cool if that happened. It would make the guild fight as a team
