Role-based partymaking
Basically like in FF14, you need 2 DPS, 1 tank and 1 healer to make a party. Lets apply the same thing when finding players for your dnd campaign! Like "okay i need 1 more player for my campaign. We already have a tanky paladin, 2 murder hobos, so... we'll need a healbot to keep us alive. Anyone wanna join?". Truly wondered why no one has ever thought of this idea, seem like the perfect way to find players on Discord
