The only way I could think to make it work would be to run along the cliff edge to the swinger’s left and then jump in order to get the rope taught. Only issue there is you better be damn sure you leg go at the right time or it will be sending you back toward the (presumably) shallow rocky water at the cliff base.
And you will 100% always find these assholes in the casual unranked lobbies. When they win they’ll be all in the chat calling the other team noobs and when they lose they’ll be in the chat bashing their team for this or that.
