Now this is a great thread idea!
Ninja that I'm upset with in regards to their actual ability, and usability in the game, and or dislike their function(can still be highly useful if not game breaking)
- Hashirama, although we get an Edo/Sage version of him eventually which as I understand is incredibly OP. I'm a little bummed at how the God of Shinobi has been relegated to being the best support Ninja(currently available) rather than a little something more.
- Hidan, despite being really great ringer in very isolated situations, I've never found a great permanent use for him. Not even ranked.
Ninja that I have some other type of issue with, be it design or mystery choice.
- Itachi, while he can be incredibly useful with his current set-up. His mystery makes his game character seem like 2% of what the manga character was in ability. Granted there will be a ridiculous Susanoo version later that costs a fortune, so it's understandable that this one wouldn't be nearly as OP.
- I guess pretty much any character that has another iteration down the line, reasons.
