User blog comment:Nick D Wolfwood/Routing for Ichigo, the power stat analysis/@comment-117598-20100819185045

I agree with Salubri entirely about Ichigo advancing way too fast. Everything about his development and power increase has been shortcuts. Attaining his sword's name, Bankai, Vizard mask.... everything he's rushed through. So all he brings to the table is raw power, unfocused against a Aizen, another character who has enough if not more raw power, with I don't know how many years of experience, who's also intelligent, cunning, and can see every event happening before it happens and plans every possible scenario in his head.

It's just difficult to say "resolve" is the deciding factor here.
