False Equivalency. Toshiro not only moves during his attacks, but his attacks are almost always telegraphed before hand by, say, a wave of the arm or by him doing something with Hyorinmaru
You are literally saying Ichigo would make a ranged attempt, see it get froze, and for some reason say "Hmmm, maybe I should try doing that same thing, but using my body". Sorry, but no. Not even someone like Kenpachi would do that...
Yes, that makes all the sense. When people in Bleach use massively powerful attacks, their energy rises! There energy definitely doesn't drain to maintain their form or perform their attack. Gotta let Kubo know
No, Byakuya is refering to her physical stated, as she becomes extremely fragile after using Bankai due to it making the AZ explosion by dropping her body temp. No, when people use their Bankai, their energy decreases. They may become more powerful or be able to use a powerful attack, but their stamina and reiatsu always either drains or the attack requires a certain amount of reiatsu. See, like, every single fight that lasts for an extended period
Actually no, Toshiro can flash freeze things without any body movement at all.
I'm saying IF he uses a range attack BEFORE getting close, that's a big IF. Regardless, I'm mostly saying he has no choice since him sitting there and waiting for nothing to happen is the least likely thing to happen in this battle and he has no other means of defeating Rukia.
The issue is though, you're under the impression that this fight is going to last more than 30 seconds, which it isn't.
