We don’t use Discord where I live. We use Viber or Facebook.
I didn’t do any Legendary Raids until another player hooked me up on our local Discord. Haven’t missed a Legendary since.
It’s easier to find players in big cities with hundreds of active players and lots of gyms. Here where I live only I am active every day, only I am level 40 and only I know the game very well. There are 2 casual players who are above level 30 the rest of the players don’t play often or have quit playing. I’m afraid I won’t be able to do any legendary raids for quite some time.
