Because for a game promoting cooperative play, promoting 'Lone-wolf syndrome' si the last thing they should be doing.

As for the Boss room: Endgame players don't really need cr anymore. They do the Bosses for fun. Out of mist, since having spent it getting more cr, they can play around in the boss room forever until they've hit their adrenaline quota. Free fun.

No incentive to get ce, because they have 'on demand free fun', no reason not to use it. A cr cost would be useless. In fact, in itself, it'd be useless. If the drawbacks get any higher than 'easily exploitable', no-one would use it.

Endgamers are filty rich. Any price you put on fighting monsters just for fighting, they will pay for it.

"Well, if they are a Endgame player they wouldn't be able to afford that room"

Bull. It's BECAUSE they're endgame they'll be able to afford. Point being they don't need the money anymore, so they can blow it out whenever, whatever.

Point remains. Free fun, no drawbacks. None big enough to warrant it.

"Then take out the Boss-Room and come up with something else! Lol."

"If my idea is so terrible then why don't you come up with something better!" <- Fixed

Because when we suggest something, we actually think about everything else involved. If we miss anything, people point it out. If something's bad, then we acknowledge it's uselessness.

And for your information, can and have.
