Sorry but I generally found the Naruto anime more enjoyable than the manga at least for me that is.Quit the anime.
Exactly what i wanted to point out.According to the manga :
1. Hagoromo died the day he chose a successor, he wouldn't be there to stop his kids
2. Ashura was Indra's equal before Hagoromo chose a successor, his Six Path Senjusu bloomed after hard training
3. Indra's MS was not the same design as Sasuke's
This is why no one takes filler seriously apart from that one guy who shall not be named
