I just read the chapter (Shash 39, I forget the chapter #) in OB where Kaladin takes Dalinar, Navani & company back to the warcamps where Dalinar investigates what happened with the 'madman' Taln. At the beginning of the chapter when they arrive at the war camp, Kaladin lashes them downward so they slowly drift down and they eventually land. It wasn't mentioned in the book, so my quick thought was, did the lashing automatically go away when they touched ground? Or can Kaladin automatically instruct when the lashing will end when he touches them. Otherwise, even though they touch ground, the lashing should still be pulling them that way, almost pushing them against the ground.
That could be explained away by saying the lashing wasn't very strong since they drifted slowly and then the stormlight ran out. But then I kept thinking, could Kaladin lash people very strongly downward and smash them against the ground? We've read instances where people are lashed upwards, specifically I'm thinking of when Szeth lashes Roion and Dalinar into the sky so that they are so high when the stormlight expires that they fall to their deaths. But just as Kalidan lashed himself downward so hard in the duel in WoR to break the shardplate (and his legs), he could probably smash people against the ground very hard. Probably just costs more stormlight, which is why we haven't seen it.
Just my musings.
