Fizz. This is not only my personal experience even though I do a LOT of raids in a day. A couple of friends of mine have the same story. And when I watch livestreams of people raiding, and just usig a pokeball for fun, they also catch a lot of pokemon. Today I did 22 raids (I counted) with 16 five stars and caught 12 in a pokeball first try. Some pokemon were:
- Giga Corviknight
- Giga Butterfree
Those pokemon differ a lot in catch rate, Shuckle has 190 and Steelix 25. Do you see why I'm thinking about it? Maybe it really is just good luck, but who knows? That's why I asked if anyone knew.
