Don't you mean that anyone with Madara's eye could summon it? I didn't see just any old Rinnegan using it.
Or did I miss something?
Oh yes, I most certainly did miss something...
...it's on the claimed list as belonging to Warren.
Duh.
Compromise? No, legalized theft. I can't think of anything worse than potentially having every rinnegan user on SL able to summon the dooms day machine. Can you imagine anything worse? I am certain that at least one of Shima Umioso's cats has the rinnegan by now, and we all know how fast they breed!
Additionally: By making it subject to bijuu challenge rules, Warren then is REQUIRED to defend 2 beasts, stop everything he is doing to deal with OOC bijuu fights. Why? Because we never did accommodate anyone who wished to go for an IC hunt in order to set up a bijuu challenge. This is just an attempt to force him to comply by those rules, rather than the ones for canon items which would require an IC hunt to engage. I think that if he had wanted to host more than one beast he would have sent himself around to challenge other hosts and attempt to acquire more.
Character control much folks?
As is, he meets the canon claimed items rules. He is active, he uses his possession. But no, you want to change the rules on him after the fact.
Word it however you like, rationalize that all day long, and site scripture and verse; it's still not right.
Have we circled jerked enough for one year on this issue, or must we go round and round some more?
It's not your decision, get used to it.
