I ment im place of the fillers they are using now, and they use fillers so they can make more money and make sure the anime does not catch up with the manga along with filling in plot holes,at least that's what i think
This right here. They lacked a lot of character development, if they built on their personalities through fillers, then I would feel really bad for them being made Tobi's 6 Paths. Han is the most mysterious of them all, his story I would be looking forward to the most.
even if they did.. people wouldnt listen to the anime because it is non cannon... so whatever feats that are performed in the anime fillers would just be pushed aside so it would be pointless... unless it has been seen in the manga people wont believe anything they can do
