It looks like there is a limit to the ferocity of creatures in battle events and battle stage. I’m not sure of it all, but the ferocity of this ankylosaurus and gorgosuchus are so close to each other and ostaposaurus too. It can be coincidence but maybe they can’t level up anymore. This also happened with different line ups.
I hope this is the limit, because I was afraid of facimg creatures with 40k health or more .Please send your strongest opponents ,mostly in fight for fumds and infinity battle stage, and maybe we can find wether this is true or not.
