Interesting, you didn't have an issue with it until Daemon convinced you that it's one hit and done I see. I'll try to present it in a different way.
This zanpakuto is far less dangerous than poison based zanpakutos. There is no way to escape zanpakuto which introduce poisons or other effects into the body which cause internal damage other than being a ridiculously high tier or having a specialized skill designed to keep foreign bodies/substances out. In fact I don't recall ever seeing a poison based zanpakuto that allows for those with healing abilities to heal against damage caused and recover.
However, if it's another weakness you want here it is:
For Forever, it can only be used on one cut at a time. This way not only is a target deciding where they are cut, but they are also protected from having to choose multiple areas of loss, IF they choose any at all.
And my app is beyond a 3-3 tier grade and I proved that already. Whatever standards you are using were not approved by members. In fact you are acting to supersede member power by using it. Post the standards you are using because they clearly aren't the ones that members like myself put into place which allows for us to choose our own tiers. I've already proven that Daemon is grading incorrectly, and according this his rebuttal he's grading incorrectly because you and the other mods taught him to grade incorrectly.
Going to an enforcer when I already know that Daemon is incorrect due in part to an enforcer wanting him to stray from standards MEMBERS DECIDED he should be using accomplishes nothing. This type of public display however does something different. It shows everyone what you would have go on behind the scenes. It shows everyone something that wouldn't be necessary were you not taking it upon yourself to toss out member decisions to project your own onto this RP instead.
App grading standards that you should both be using:
http://www.bleachstory.net/t4548-app-grading-standardsAccording to the standards that you should be using this is a 3-2, 3-1 app unless I wanted leadership (which I currently don't). The only sections you should be looking at (again they are appearance, personality, and history) flow with each other and play off of one another (note RP sample doesn't have to flow with the others), show a great amount of effort and surpass the shortened paragraph requirements. Post the standards you are using for all to see or throw them out because they probably shouldn't be used at all.
