(I'm talking about between species here) I know we all like our big carnivore death battles, but, in nature, I'm pretty sure that carnivores wouldn't fight each other to the death unless really hungry. Like, for example, A Ceratosaurus and a Metriacanthosaurus would probably not fight to the death over food/territory. I'm not saying remove the death fights, but maybe less common? I'm sorry if this has already been addressed, I didn't check.
Yes please. Especially predator prey fights shouldn't always end in death. I'd love to see some herbivore escape sometimes.
