This is a very coddle toxic game where the community is perfectly fine with calling out people that demands competence from the rest of the party and are also very protective of players that are lazy and/or lacks basic understanding of their job and game mechanics and is in content where they shouldn't be. Due to this reason, the only options left to you are either try to vote kick the leeches, which is on a 4 hours long cooldown. Vote abandon, which isn't likely to go through. Or just leave by yourself, in which case you'd have to eat a 30 minutes penalty for.
