Come on Nintendo and Niantic - the raid battles for legendaries especially and high levels is really frustrating and not very e-community friendly. There is no way to communicate to other players to get a raid battle going. I dont really have Pokémon Go playing friends so groups arent an option (and putting 20 people together is ridiculous). Since there is no alert that anyone else wants to battle a raid, there is no reason to head to a gym, and worse if you do since you just sit there hoping someone will show up (or like 15 people, randomly, in a place where few are playing)... Generally, the new options feel more oriented toward profits vs gameplay, please remember your players....
