I said right in the first post that I was not talking about items, merely jutsu. Also, at no point did I or anyone else say, "Ok, let's go over the rules we are going to force upon everyone on SL." if people want to keep rping that they have their claimed jutsu they can, they don't have to follow our rules, just like how people can claim to be fantasy creatures when others don't like it. It seems incredibly presumptuous to make a multi-paragraph rant about how we are trying to control people when that was never the objective.
As for Eric's list I agree with Edo Tensei, Hiraishin and Body Recreation. I do not agree with Dead Soul Consuming Seal, that's a suicide technique that not even Edo Tensei can abuse, I say if you want to take your opponent out with you then do it. I also actually don't agree with Raiton no Yoroi because how do we limit that? Dozens of people claim it, who loses it and who keeps it? I don't think there is a fair way to decide that. I don't know what he means by corpse control, and would like to see that jutsu page.
By Oro's body substitution I assume you mean this?
http://naruto.wikia.com/wiki/Orochimaru-Style_Body_Replacement_TechniqueIt's kind of hard to limit things that aren't already claimed I am now realizing. I can't think of a fair way to say who would get to use it and who doesn't, unless we just want to say no one new can learn those jutsu without being taught by a current holder, but then for Raiton no Yoroi there would just be a list of like 75 people on it.
