My whole point is asking why they thought they needed to escalate the ecosystem's arms race by making things that had no place to be there that eventually warranted more insane monsters. In our world, the food web is balanced and everything has their own ecological niche. When the environment changes or new species migrate in, some who can't adapt die and then the remaining ones will change to fill in any empty niches. When you introduce something that has no business being there, you upset the whole balance. Like how Australia decided to introduce cane toads to solve a beetle problem but the cane toads are poisonous and nothing can eat them and they went crazy on the environment and left the beetles alone.
The gazelles are kept in check by lions, there's no real reason to add the giant, flying, fire-breathing wolves unless you made them either because you felt like it or because the ecosystem is being thrown out of control by the humongous, antlered, lighting-calling panthers you made last week.
"It's a fantasy game and it's just a reason to explain monsters" is the meta excuse. But the Ancients didn't wake up one morning realizing they're in a fantasy game so they have carte blanche to recreate Street Sharks. Though I doubt we'll learn of how it got this way unless they make a Tales of the Dawn entry on the origins of Elpis, it was probably a slippery slope that led to where they got to at the point we arrived. I'm sure it started with better intentions but it ended with researchers wanting to see a bunch of things fight and creating life to keep up with the trends. When it's normal, you don't see it as a bad thing and I'm sure most of them see it that way. But then you have Hermes who was in the wrong position for someone cursed with caring too much and he decided he was going to end the world over it.
