I wonder if Jagex should do a couple instanced versions of a boss per world. So rather than having 1 Kree'arra per world, have 5 or so. Place a portal at the door and you could enter one of the 5 instances through it (allowing you to see how many players is in each instance of that boss before going in). That's just an example off the top of my head, but that sort of thing would help; Bandos is full pretty much all the time in every single LS world and I know other bosses are generally pretty full. I don't approve of crashing really, but it's a dog-eat-dog world, so whatever.
