User blog comment:Salubri/Final Fight: Reflections of an Unrealistic and Ridiculous Battle/@comment-1669175-20100129181302

Just two really quick things. Just because we don't know much about Aizen's history yet, doesnt mean we won't. We learned more about Tosen on his deathbed and through the interactions he had in his last fight. We yet might see Aizen's history played out as he fights/injures someone a little closer to him.

We also mention that we are seeing the most powerful and elite of SS go down. We arent. As I mentioned earlier, we are seeing two relatively newcomes and a few vizard. We weren't led to believe (or at least I wasnt) that the Vizard (maybe apart from Shinji) were truly anything to be feared. We just know at one point they were Captains/LTs. That doesnt mean they are the best of the best. There are clearly distinctions between the Captains as to their level of power. And I understand the boost someone is supposed to get after Bankai (10x) but that is from THEIR starting point, not everyone elses. It is relative. We also know that Bankai's tire out their users, especially when they are overly large (Komamura), and both Komamura and Hitsugaya had been using their Bankai's for quite some time very recently. So I would assume that they are not 100% going into the battle with him. We also know that a Bankai isn't always all it is lived up to be, as evidenced by an increasing number of people attaining them in a fairly recent manner compared the once in a few generations that Byakuya mentioned (Ichigo, Renji, Ikkaku). And they mentioned that it takes hundreds of years to master them, something Hitsugaya hasnt had, it recently evolved into a more stable form, but by no means does he have a mastery of it yet.

You're right, no one has a hit on him when attacking en mass, but is that the SS specialty? Most battles are 1v1. Shinji (trickery) or not, did manage to hit him one v one. you could argue that he was just toying with Shinji and letting him hit him, and testing out his zanpaktou before hitting back.
