Saiken's Glitch Gap

Do you have any more screenshots as proof that it didn't go through properly? There's a bugs section where you can report it as well. From the screenshot you've provided I don't really see what the problem is.

I think a lot of people will disagree with the usefullness or lack there of the Bijuu's. There have been instances where they are quite strong or were. The meta itself just doesn't suit playing them rn. Distributing damage evenly would make them very weak against AoE chars - more so than they already are rn, which is one of the easiest ways to kill a Bijuu char.

I don't right now, but I swear to god it's happened a lot of times before. It just won't trigger when a harmful skill is used on him. Please, inspect further into the problem.
