OK, a couple of things that people have noted are wildly inaccurate.
Soifon's Shunko is not a one-shot. She released it when her suppressed emotions finally overcame her, after only employing it once. Not the same thing at all, for the record.
Ichigo's only strength being Zanjutsu? Utterly untrue. He learned Shunpo at some point during his 3-day Bankai training, and was good enough to match Byakuya - who, don't forget, has only been using Shunpo for the past hundred and ten years.
Kido he clearly doesn't know, and Hakuda he doesn't use - although, given that he has been stated to beat a national karate champion at karate on one occasion, one might be forgiven for expecting him to be pretty good at hand-to-hand fighting.
So, of the four forms, he excels at two of them, hasn't been taught a third and chooses not to use the fourth. That's not bad for six months as a Shinigami.
