Well, the other options are recruit chat and Discord. Warframe Discords that aren't the official one are so fucking cringy and degenerate that being in them for more than 3 days makes me want to ventilate my wrists. Sadly, recruiting chat is no better. Aside from the chat mod R3d P01nt being a sperg who can shut you out over the smallest slight, it's a complete pain in the ass. Just trying to find three people with the same relic during the current Prime Access already takes long enough sometimes. Add another two people onto that with the added requirement of them not being fucking braindead? Good fucking luck.
