I think what Daiske is trying to say that while everyone may be aware of this issue, the reason it could exist is because no one has come up with a better solution for how to handle it. While we all may understand and relate to your frustration, the only way this can become fixed is with a new implementation. Pitch an idea, maybe we can get it presented to the devs and have it fixed.

The fact that multiple interrupts get used on the same target is tricky to handle. I don't think the coding allows for taking into consideration that many turn in advance- I'm betting it does it because it detects whether or not there is an attempt to cast jutsu and targets based on that. Until the interrupt actually goes through - they're still targeted for it.

I don't know if it would be possible to ALSO detect an interrupt already targeting the jutsu and avoid them from stacking that way. But there's also the problem of if the interrupt isn't fast enough or is stopped by the enemy before you can interrupt.

I definitely agree the priority system on AI interrupt is atrocious. As a lightning main, there is nothing I fear more than seeing giant rasengan from a wind main. In ranked my AI never chooses those targets and I tend to eat the damage every time. I notice a lot more emphasis on interrupting barriers, fellow interrupts, and usually hinata. Rarely does it stop the high damage jutsu I'm actually afraid of. it's a pretty game changing decision and I feel there's a lot of ranked matches I would win instead of lose if the interrupts were prioritized better.

How do we determine priority though? How does the current AI system even categorize priority? Can it calculate the effects before it goes through and prioritize that way? Otherwise it would be likely subjective to give a certain priority to each individual ninja. What one team might consider high priority another might not.
