While I've been mostly playful about certain things that have been mentioned in the thread, I can't help but agree with Rusaku about the entire situation... well, with his situation... to an extent. While I heard that you understand that you knew of the rules for the alts and whatever, you still went and did the challenge.
Couldn't you have simply challenged Shadow after his grace period was up? Or is the no alts rules pertain to the entirety of the SL realm? If that's the case, it's rather odd. If a single person can basically control all nine, why can't an alt, that's already been established in the IC/SL world, go for a beast.
Granted I'm just diving in with no knowledge to how shallow/deep this rabbit hole might be, but if that's the case, one can simply cap it to two an owner if they choose to go that route. Because, like I said, if somebody can have all nine, why should it matter if the alt challenges for one while the main is doing the same?
In the case of the whole dropping out thing, since (in my opinion) Zera had basically lost already by the time this was brought to Camel's attention. I'm not being biased in my opinion of the outcome, but it seemed pretty straightforward to me. I haven't read Shadow's fight with Nanashi, so I can't really give an opinion on that when the latter dropped out. But, since it was not a bracket tournament, I believe the Shadow should at least fight the Biju to subdue it. It could be full power or weakened due to the fight that happened beforehand, if that even makes sense. I could say the same about Tobias. Obviously, both shouldn't have a problem considering who they are. But that decision would have to be up to the Biju Council, just to figure out if enough fighting was done before the dropping. That's just my two cents for the day... maybe for a few days.
