Give how standard season formats have been changed, I think it would be best to release tournament exclusive dinos into the wild. It would help people get dinos they want to use to a usable level, and encourage more hunting.
Here’s where I think they could spawn.
Diplod: L1 (it’s the worst zone, give it some love please)
Dsunga: Dawn/Dusk global
Blue: Arena incubators (not really into the wild, but it’s a bit of a special case)
Might not be exactly that, but let them be obtainable from methods other than sanctuaries and waiting for events, please.
