No group, no luck. Tried a bit with Articuno, simply no luck at all because there were never enough participants. At best, there were five interested participants (including me), but that was in a busy area on a busy day after a good while of waiting. Two of them didn't participate in the end, probably because they thought it was too few people. Raids are miserable if you don't have a group, and legendaries only amplify the problem. I might join a group but I haven't found one (although there probably are around here), and I don't use WhatsApp anyway so that's probably a problem even if I find one. This is some really bad design on Niantic's side: Good for really active players but sucks for a lot of other players. Maybe it's better in huge cities though? I mean, I live in one of my country's biggest cities, but it's pretty small on a global scale.
