is much more forgiving imho.
You almost had me until you said that.
Why does it need to be forgiving? Why should it be easier for them? If they want to be hosts, then they should know they signed up for the task of defending and protecting themselves. 3 months versus 2 isn't a whole lot different when people can post once a week and make a fight last a year before they even scratch each other. Even in in-game time, 3 months (9 months) is almost 16 less years than it took two of the three Jinchuuriki that had more than 2 minutes of screen time to master their beasts. I know the majority of people don't use in-game time as how they age, but it's easier than making up numbers to prove my point. I don't think those who obtain, hold, or seek to obtain a Bijuu should be coddled like newborns.
If you're talking about a biju match, the moment that match starts, the host cannot use any powers that they would obtain over the course of outside RP. As far as regular fights go, it is very much similar, that they can't use those time powers until after that fight is done.
If the task of owning a biju is unforgiving in its entirety, then why would people who actually need to use thier power bother getting them? It would just get taken away by someone who doesn't actually need the power sometime during the tenure. Considering all of the rules and such involved with being a jinchurikii, why bother getting a biju if you actually need to use its full power to stay competitive?
Having hosts wait 3 weeks or wait 2 weeks, if they get into a biju match that lasts for that kind of time, I guess is hardly a difference, but then, that makes the aspect of making hosts wait a certain amount of time to get their power-up kind of moot then doesn't it?
If people abuse the time in that kind of fashion, to get into a rigged match for the sake of dragging it out during their entire (or even a large portion) of their tenure, shouldn't there be some sort of penalty for that? Shouldn't that kind of misconduct, which defeats the purpose of mastery times in the first place, be something of a red flag instead of justification to extend the time even more?
Besides, coddled like newborns would be giving them all the powerz on day 7 or even sooner. >_>
