I agree, a lot of my party members were using jump to get down from a cliff and they hit hard, took damage and went prone.
I haven't done this yet, but I would have assumed there would be some sort of skill/ability check to bypass some of the effects of the jump (go prone, take less falling damage,...)
The targeting circle you see when you use jump should have different color tint to let you know how dangerous that jump can be.
Your on a cliff, you want to jump down.
You select the jump action, the targeting circle pops up and depending on where you want to jump while using the cursor to pick a landing spot, the jump circle could turn yellow or red to let you know that the spot you picked to land on is gonna hurt or possible kill you.
You should still have some skill/ability checks on those rough landings and you should see the dice rolls on screen...I didn't ask them if they had any checks but will ask if it happens again.
