As for first doubt. Nope. We have WOG for it. We can shut him down at any moment.
We can't shut him down from using his powers if we tell him to use his powers and let him use his powers. Or rather, we can shut him down
after he uses his powers in a way we disapprove of, but not before.
We know Dazarel is cunning enough to use telekinesis to crush hearts or even perforate eardrums when he deems subtlety to be in his interests. He'll
at least get one shot with his powers before we lock him back down, and every time we let him free we give him another shot.
The ward can't be impenetrable and penetrable at the same time, and the goals of using the dragon's power and
confining the dragon's power are mutually exclusive.
It was stated that seal is:
- Safe: no chance of influencing Kakara via psychic tricks.
- Secure: no chance of it being disrupted. Neither by internal or external manipulation.
- Comfortable: as Kakara could always mute him, so no unwanted commentary or disruption of daily life.
- Fully controlable: a blank wall - and which we decide how permeable it is.
If we're trying to tap the dragon for power,
by necessity we will need to let the barrier down. An invincible wall is an invincible wall- right up until you decide you want to be able to look out the window and cut a hole in it.
After that? Not so much.
...
Can You deny, that Dazarel toyed with all strongest exiles and won without scratch, despite his nominally much smaller power level?
Effectiveness multiplier, there.
And if it turns out that his effectiveness multiplier is from "being a dragon with a dragon body," not from some technique we can learn?
I mean, Namekians can regrow severed limbs in moments. That doesn't mean we could imprison a Namekian and interrogate him until he taught us the secret of limb regeneration.
Please note what exactly was said in my post. I was repeatedly saying "we don't know", and listing some optimistic scenarios while explicitelly noting that those are optimistic ones. Please do not re-interpred what I've said, OK?
The thing is, your argument "we should do X" and "X is the only path to victory" is predicated
entirely on those optimistic scenarios. And you're saying we're screwed if we don't do X.
Are you saying you think we're all screwed unless we follow this very specific path that is only even available to us because of an unforeseeable combination of weird dice rolls? Or are you overstating how pivotal these dragon powers really are? Pick one, because it's got to be one or the other.
I believe it was confirmed in discussion that followed. There was plenty of back and forth about how safe and secure seal would be. And the answer was in general area of extremely secure.
Yes, but that was in the context of us, y'know,
not letting the dragon have freedom of action. A lot of prisons are very secure, if you don't let the prisoner out to do something for you. Once you give the prisoner means to reach past the bars and walls of his cell, any security measures you may have get a lot weaker.
Frieza was supposedly the strongest person in the Galaxy, and your power level couldn't really change beyond what you were born with.
Canon is full of problems like that...
Eh? I don't agree. I think the core point is still pretty solid- namely, that the "rules" of galactic ki-using society were pretty predictable and well known, until suddenly they
weren't, after being exposed to a few destabilizing new 'technologies' invented in an isolated backwater and combined in useful ways. Namely, highly effective power level training, and ki sensing.
...so we really shouldn't expect something like Overdrive to be a unique thing based on canon details. That doesn't make it useless*, just not an Ace in the Hole like Spirit Saiyan, higher level transformations, or fusion
*although it seems to be so compared to Jaffur's technique.
Actually, I think Overdrive is likely to be
MORE useful as an ace in the hole. Ki compression increases your effective power level by some fixed percentage, and if it's 5% at Poor, I doubt it goes up much past, oh, 50% at the highest levels readily available to us. Good, potentially decisive against a roughly equal opponent, but not enough to let us 'spike' and punch vastly above our weight.
Tactical evidence supports this; during the battle, Apra was the one who was doing the most to really hurt the dragon as far as I can tell, and as Poptart confirmed, it would have been Apra going into maximum overdrive that would have given (the rest of) us a chance to survive if Kakara hadn't pulled off Spirit Saiyan.
What Jaffur's technique does is provide a significant power level boost for strong-willed individuals (like both Jaffur and Kakara) that is
persistent and sustainable. Which is very useful, very useful indeed, but only decisive against roughly evenly matched opponents. Or if it turns out to be a prerequisite for something more significant like "ritual-free ascension to godhood."
