Ishida thinks he's being sly by pretending to work for Bach when in reality he's doing it to help bring him down. But unbeknownst to Ishida, Bach knows what Ishida is trying to do and Bach, after using Ishida for a few minor plots, ends up stealing Ishida's powers and becomes even stronger.
Ishida has already lost his powers once.
It would be really anticlimactic for him to lose them again.
Insanecyclone posted exactly what I was thinking.
Now it's time for Soul Society to recruit some teenagers with attitude--

Oh.

Like how Rukia lost her powers and regained them?
Like how Ishida lost his powers and regained them?
Like how Isshin lost his powers and regained them?
Like how Ichigo was afraid to use his powers but regained the courage to do so?
Like how Ichigo lost his powers and regained them?
Like how everyone lost their powers in the zanpaktou arc and regained them?
That only applies to Bach, because he laid the seed and created the Quincies. That means he essentially can just steal powers as he needs them and I'm certain the stealing of bankais has a LOT to do with it.
I would bank on the power-theft, Bach's heritage (is he of the royal family), and the shadow realm all being very major plot points in the near future. There has to be a reason that the Spirit King is showing such an interest in Ichigo and in what's going on.
He DID manage to explode and nearly kill a captain in one shot back during the SS arc ya know. Sure he got shat on afterwards but the potential is there and im presuming the pureblooded quincies were better at bringing it out than Ishida's dad.
Another way to look at it is Ishida hasn't actually been well trained much. He had to basically learn from his elderly grandfather and essentially make shit up from there.
He got a short bit of training from his father which he didn't even finish but that's about it. I think I even recall his father saying that Ishida is sloppy at everything.
Tossing Ishida into a well regimented military probably did more to refine Ishida's raw power than anything.
TLDR it's not that Ishida got strong so much as he's finally been trained properly vs mimicking stuff he saw as a kid.
But what does this all do for Ichigo? He didn't need a "reason to beat the bad guy," he needed to get stronger/fix his sword.
From this I really just see him being weaker in that Bach can maybe take his quincy powers away?
Idk, just not seeing how this really makes progress.

Even if that is bullshit, your sig is always hilariously appropriate.
I definitely agree with your assessment of his potential, but I don't understand why someone would make that statement prior to training. I'm not convinced most people would say "You better watch out because this untrained pupil is fucking badass!".
Well, a few advantages:
1. The Shinigami were probably worried he would turn against them if he learned of this mid-battle
2. He needs to be aware of Bach's ability to snare quincy powers
3. We really don't know what this means for how Ichigo has been using his power (Remember the congruence between his Zanpakuto's avatar and Bach?)
4. He never knew of his relation to Bach and Bach's statement may make Ichigo reluctant to attack him (Remember when everyone speculated that Bach was Ichigo's father? An incorrect suspicion, but one made nonetheless!)
5. If opposing powers keep each other in check, could this mean he inadvertently sealed one power using another?
This nigga is going to be able to have blut up while in his Vasto Lorde ressurection while doing Getsuga Tenshou with a Cero coming out of his ass and have the willpower of a human. NIGGAS BE FUCKED
He has to learn all of these probably before he takes on Spirit King. Once he kills Bach, he goes all highlander and gets full power of all the Quincies.
Grimjow will train him with his hollow side.
His Dad and Urahara with the Shinigami.
Uryuu/Ishida with his Quincy.
Don Kanoji with his human side.
