Objectively though, Rixis is probably the most in need of balance, being the strongest compared to the rest of it’s rarity. However strong Brontolasmus, Entelochops, and Diplodocus are, and there can be a case made to nerf any of them, Rixis is even stronger still. If Rixis doesn’t need a nerf, then nothing does, so I have to disagree there. It doesn’t need a big nerf, but it needs something.
You bring up some good points about Suchotators resistances. However, @Funtime_dino has good points about it’s stats. Its attack is on par with most rare hybrids, but it’s HP is far higher than others with a similar attack stat. And it doesn’t even need a strong attack, it can bleed and stall! So I think part of it’s attack or hp (maybe mostly HP) has to give. This is a creature on par with the strongest “balanced” legendaries, but it’s only a rare.
