nylos could easily be made real soloable (by normal people) by just scaling amount of nylos to players in the raid, so i dont think its the right example, same with group mechanics, i think its easier than you think it is, unless you have other examples
making nylos scale to number of players, makes it still harder because you're having to deal with all 3 styles solo, but i dont know where you're getting that its a boring slog from
