Noaoki Yoshida plays alot of Rift. Rift has a generic claim system like most every other MMORPG. But it also has some other type of system that kicks in when a Rift event occurs.

I can't break it down technically, but every monster created from a Rift opening event is able to be attacked by anyone. When they die and drop loot, even if you helped kill the mob, you can't always pick up the loot bag. I haven't played Rift in a while so I don't remember if you still get some XP from helping make the kill or not.

Anyway, my point is that Naoki Yoshida may be taking a page from Rift with this new "no-claim" claiming system. It is a decent amount of fun, believe it or not. Bounding over a hill to see an adventurer surrounded by spiders and charging in to tackle a spider (or two if you line up the tackle real good) and help out sounds pretty adventurous if you ask me.

But time will tell. I'll get upset when this system actually starts being a pain in the ass, versus preemptively feeling the pain 1 month ahead of time.
