I think some creatures should still keep total immunity, such as the synapsids (Dime, Seco) and ostriches, but their hybrids that are not synapsids/ostriches should not have it.
-Ardentismaxima, Geminititan, Indominus, Erlidominus, Tryostronix, Ardontosaurus, can all lose total immunity and have like 2-4 partials each
-I have not included Pterovexus and Monolorhino in this list, because they will be virtually useless without full immunity, so unless they are greatly buffed in other ways to compensate, they should keep total immunity
As well, all creatures with immune to DoT should lose immune to DoT, except for the turtles. This will make bleeders more relevant if they can bleed mammoths. None of these who lose DoT immunity should be buffed to compensate, they really don’t need it
Some other partials should also be removed if they don’t make sense, but if needed those creatures should be buffed to compensate.
