So far I've gotten G-Max Corviknight, Drednaw, Centiskorch, Butterfree, and Sandaconda from raids.
Got a few of Corviknight, Drednaw, and Butterfree. A LOT of Centiskorch. Just one Sandaconda though.
Catch rates are quite abysmal, and frankly, it's irritating.
Also what's more frustrating is when I get a G-Max raid on my feed only for it to have a Link Code. Seriously, those should be private rooms that only your friends can see. Had a G-Max Gengar, Duraludon, Hatterene, and Machamp on my feed with Link Codes.
