The AI has some really annoying fails that make the game a bit frustating at times.
For starter the targeting system, for a time I had Neji, Guy and Zabuza in the same party, and the AI would target the 3 interrupts of the party on the same target on the same round, that is a waste, after all before the animations starts the AI already decided the result so if it knows that it will alreay interrupt the spell why target it again with another interrupt? Make it choose a different target.
AI will always use a healing mystery if even 1% of the team health goes down, its a waste of cooldown and mysteries, because heal has a 3 to 4 rounds of cooldown, and the passive heal would heal that easily.
AI will always prioritize Sasuke no matter what ninjas you have on the team or even other teams, I run Gaara in one team and Sasuke in the main team, and the AI will use both field spells on round one, WHY? That will just lock Gaara for 3 rounds, and the c*ra used by Sasuke could be used on Hinata Mystery instead.
Almost forgot the "target the only ninja that cant be comboed" while the other 3 ninjas in the opponent team just sit back and kill you, and im talking about mysteriess targeting not the main atack because that one at least will atack the target right in front.
That and focus mysteries on clones instead of the main body, what a wast of combos and damage.
In the worst case scenario let us have a priority list that we can do for mysteries.
