User blog comment:SuperStrawHatSaiyan/Are You Gonna Fix It, Toei?/@comment-4605926-20130104171515

Personally, I haven't encountered the differences you speak about between the Manga and the Anime, though that might well be due to my lack of careful attention to certain details in the Manga. I do though check regularly every Episode's "Anime Notes" section on this wiki because it is important for me to know how close to the truth the anime's episode was. I think that there are certain situations (mostly insignificant ones) that are being revised on purpose by Toei Animations, I believe yours are not the case. I trust that once certain facts come to their attention, such as significant technique differences, they will fix them in future episodes. I think the production team just doesn't analyze and portray the manga's chapters as many would hope they would. Such a scene could be Zoro cutting through steel in one of the filler episodes (though that would be slightly more understandable since a deeper general understanding of the story was required in this case) http://onepiece.wikia.com/wiki/Warship_Island_Arc.

So to answer your question, I'd very much like to hope Toei would fix those mistakes in the future, and furthermore just stick firmly to the manga and refrain from changing even the slightest of situations so as to avoid any bigger and more significant ones as well.

On a side note, if you will, I'd very much appreciate it if you explained exactly how different the activation of Luffy's Gear Second was between the Manga and the Anime as I personally hadn't noticed it.
