I have to ask. What problem is it exactly the Bijuu are causing? I'm looking around, and I'm seeing nothing specific pointed out.
Is it because they are too OP? Well, so are a bunch of other things on SL, it has always been that way. Ever since I can remember there have always been people and things that were over-the-top, unkillable, and other "OP" things. Yet, good RPers could find a way to win anyway so there is that.
So then, is it because people are fighting over them? I think that's the point. They are there to stimulate RP and country relations. If things about them were peaceful, then it'd be really damn boring. While I agree that the challenge system should be worked on or removed, the bijuu themselves are not the problem.
Are they interfering with non-rpers? This is a silly thing to say. Why the hell would non-rpers care? Are you seriously trying to say that non-rpers are being affected at all by the rp world in SL? That makes no sense. At all.
So someone, please enlighten me as to what the issue is at its core; specifically why bijuu are the problem. As you can see, I really do not know what this topic is trying to argue and why.
As a side note, Uetto, I'm not sure where your memories are founded, but I always remember people completely disliking vampires and werewolves and other things. The only reason some of them were even mildly accepted was because they RPed well and within the rules of the Naruto-verse. Even the most outlandish abilities still need to be justified with "chakra magic" or some such for anyone to even think about it seriously for half a second, and even more justified were they to use it in some sort of battle. That's how it's always been.
