Anyone care to play devil's advocate and explain how this is possible?
First, check my screenshot https://imgur.com/a/R9KeH2q
During an Arena battle, my opponent's Hal level was a 657. This was during the x3 Hal event, but still a bit high! That gives their Hal an organic level of 219, but their other birds are only 89.
I didn't get my opponent's total FP, but it was only the 3rd game of the Arena, so their FP would have been similar to mine, give or take maximum 50 FP either way.
Here's the kicker... those three birds in the screenshot total 835 FP alone. My total FP with all 8 birds is 857. That's a gap of just 22, which means my opponent's other 5 birds have an average level between 1-15 each.
Smell the fish!
