Or there could be another kind of battle down there, so let's say titan EX for fun, and one dps falls down, and to get back up he will need to fight something down there, and the strategy would be that "oh one of our dps fell down, we need another dps and one healer to jump down too to get him back up alive" making the fight at the top a bit harder for sometime while they are on their way back.
Oh that's why I meant, not just an empty path to get back on. There'd be enemies and other stuff to make it hard to get back, and why not having to bring someone along? That sounds cool.
