Currently, SE is attempting to lower the party size from 15 to 8. This is a much needed change, as killing NM's with anything more than 8 people is just embarrassingly easy anyways. Hell, it's embarrassingly easy with only 8. They also mentioned they will make NM's EASIER once party size is lowered... That'll suck. They're not even a challenge now.

Now, to my main point for posting; allowing anybody to attack a monster makes max party size irrelevant. They want to make the game balanced around either 4, or 8 man parties but they want to allow anyone and everyone to attack any monster at any time? Well... Then you got twenty parties of 8 out there wailing on an NM... It's now broked. And don't pretend it won't happen if they remove the claim system.
