I mean just look at these stats… And remember that Poukan is part fierce, the ones that are supposed to have the highest attack power. Dio beats her in every way except speed, and has a 2x attack to boot! Really, health and armor should be the only stat higher on Dio.
Following the actual game logic, and considering there’s an exclusive in Poukan’s lineage, she should have an attack equal to or higher than a resilient, and a higher crit. And if Dio is allowed to have a Resilient Rampage, Poukan should have a 2x attack.
I won’t even get into the argument that a shield shattering counter attack is almost worthless if the only moveset she has is perfectly countered by the shielded dinos. The only way it would have true value would be to give her speed immunity (and we all know that’s not likely to happen, even if it would make her more viable).
