Collection So Many Bios

[cappatacus]

I've gotten four Bio Exorcists in the last month. I've maybe pulled two other gold fighters. Is there a way to maybe reduce the odds of getting a certain fighter once you've already gotten it (say, four times,) from a relic? I think people have brought up similar complaints, and suggested a trading system, but I get that making it easier to have a full collection could throw off the game's economy.

This really isn't that big a deal - worst case scenario, I use them for skill points, use one, and feed the others for evolution or smth. I hope I don't sound like I'm whining lol

I too would appreciate some sort of system that weighs new fighters over repeats.
