Rajakylosaurus Counterattack fails

Hi!
Since last update, I was cheated with muy Rajakylosaurus so the counterattack does not pierce rivals amor. It’s a big inconvenience…
It’s a big or it’s going yo be this way for this dino?
Thanks…

Did your opponent have shield up? If so, the counter attack deals less damage.

No, last one (for example) was an Allosinosaurus…
