1.I think it would be a good idea if you had puzzle pieces in the maze.i think this would improve the importance of the maze because you would have to go farther into the maze which would challenge the players more to not get hit by the traps.The puzzle piece could be anything.
2.The most important thing i'm requesting is this: I wish you could interact with other players more, mainly the players in your own guild.
I think you should be able to interact with other players more like you could trade items with other players from your guild. I also think you should dive into guild roles more, i myself created guild roles for my guild and it is currently working fine.
3.Finally my third idea is, for the guild players of KOT-you should add a guild dungeon that every member would contribute to, and the opposing guilds in guild battles would raid the opposing teams dungeon.
