The main issue i noticed is linked to the fact the but(ton of the mystery in cases like kurama or konan do not get enlightened until the standard attack that make it proc does not get resolved in the animation. The server had it calculated way before, so if the but(ton enlightens together with the server response instead of waiting for the animation to resolves the issue would instantly disappear. The same is with kushina or fuguki kind of ninjas. If the but(ton enlightened at the beginning of the enemy combo streak instead of waiting for the whole 3/6 hits to actually deliver the * in the animation before being available to be pushed the issue would be solved for them too. Unlink the ui and the animation and only link the ui *ons to server response and both the issues are solved.

It's all linked to standard attacks. If they increase the preset time between a standard attack and the following standard attack by 1 second all those issues or at least the largest part of them, would be solved. Yes all the battles would be slightly longer but if is the only way to solve the issue, do it.
