So , Uryu dies, Chad probably dies, who's Orihime going to die to now? Considering how inferior all of Ichigo's friends are compared to him, they're just gonna die.
Besides even if Ichi kills Bach, so what? Then you still have Hashbrown with all of his powers basically being the new Bach. Even if he hasn't fully grasped the use of it, these are still the same powers that sorta killed Yamamoto, Ichibee, etc...what hope does Uryu stand? Not to mention there's a rampaging colossus outside and a death dude who can't easily be killed. Seems kinda dumb despite the hype that hollow powers are cancer to quincy that Gerald isn't more hurt by the vizards.
