>>52538076I've caught just under two hundred of Larvestas in the XXL category, and none of them ended up being max size.
Size hunting is a fucking pain, and the Humungos power does nothing.
At least with Shinies you know when you've found and gotten one.
But filling a whole box of newly caught pokemon, and then having the Mesagoza hiker lady give you the bad news that none of them are actually max size, is very demoralizing.
