I think crocodiles are in a pretty tough spot right now. Really they always have been. I think the problem stems from having to use the bigger lockdown move separately(aside from the generally low stats). Pinning strike is fine, especially on other dinosaurs, but the pinning is supposed to be the signature of the crocs. It usually gets them killed trying.
Ideally a new passive should be created just for crocs and their hybrids that pins the opponent for the entire time your croc is tagged in or alive. This would give them a huge usefulness and free up a slot in their much to be desired ability set. It’d go a long way combating the DG2 abomination that ruins majority of matches.
