That megapost is bullshit anyway. It keeps claiming stuff like...
"Compare it (ichigo's behaviour) to the wimpy kid who didn't want to take the responsibility of protecting everyone because it was too much of a hassle."
Using that one panel, when that isn't even true of his character at that point. He was already sticking his neck out for chad, rukia, his sisters, whoever because that's just who he was anyway. The whole protecting everyone thing is the point of his fucking character and his been since the start. All that panel was was his dumbass, immature posturing.
nabbed this from the bleach wiki-
So what exactly taking that out is his development? He apparently learns to fight with his brain, sheds the tough guy act (sometimes), learns basic human empathy (what the author of that post calls a "power to read people" lmao) and becomes OK with taking orders from soul society and killing.
It's even funnier when you consider that there's multiple panels saying that he "never changes" or is "still the same as then" when talking about ichigo, heck 476, the chapter he used at the end has rukia saying exactly that.
basically it's all BS written to manipulate people into thinking bleach is better than it is. You could make a way better post in this vain about Luffy or even Coby from one piece without even trying.
