I was going through several Bleach Forums and I left some good comments about Uryu, then everyone bashed him and called him weak. But seriously, Uryu isn't weak, he's easily one of the strongest characters out there (including Shinigami).
Think about it, if Uryu was fighting a Shinigami, in the long run the Shinnigami would lose. Uryu is really fast and athletic, so all he has to do is dodge the Shinigami's attacks, and eventually his opponent will get tired/weaker, then all Uryu has to do is gather the Reishi the Shinigami wasted and end the fight with an arrow. And also, think about the Quincy items, plus Uryu's tactical genius, no Shinigami below Captain level could defeat him. What if his bones get broken, two words, who cares? He could just use Ransotengai. If a Shinigami's bones get broken, that's it, they're done. His Hirenkyaku makes him as fast as any Shinigami (or in his words, faster, since Hirenkyaku is supposedly faster than Shunpo).
Now if the above paragraph doesn't convince you that Uryu is strong, let's go back to the Soul Society Arc, Quincy Final Form. With one arrow, he annihilated a Captain's Bankai and nearly killed the Captain (now this is a Captain that not many people could face because of his high level intellect, inventions and poisons)........and that shot missed, imagine if it had hit......bye Captain Kurotsuchi. Now imagine if Uryu could have used that power (just once more) in Hueco Mundo. There is supposedly more Reishi in Hueco Mundo than in the Human World or Soul Society, so Uryu would basically be unstoppable. This is why, Quincy Final Form apparently makes Uryu above-normal-Captain-level in Soul Society, so it would make him about as strong as the more powerful Captains (like Kyoraku, Ukitake, Unohana and Yamamoto)in Hueco Mundo, or stronger. Ulquiorra had a "sea" of power, Uryu would have had an "ocean"!
Point is, don't disregard Uryu as weak, he's actually pretty powerful.
