The problem is the RNG seems just TOO random. I see lots of people complaining about the snake, and even the rare one. I’ve seen (and darted of course) several epics (over 10 at least) and tons of the rare.
On the other hand, I am yet to see a single turtle at a park, considering it’s been a park spawn for months now. I’ve got a few in the wild, months ago, and never more. Haven’t seen a single one probably since November.
