Jumping down is fine. You take damage from falls unless you cast Feather Fall.
Jumping up is ridiculous though as is jumping to disengage in combat. I'd rather see more realistic climbing to reach elevation and jumping in combat should be the polar opposite of a safe disengage and trigger an AoO.
Exactly what I'm saying. Thank you. Lae'zel is like the Hulk. She can leap 30 feet into the air whether up or across huge gaps. I get that some characters might have some magical enhancements when it comes to jumping, but right now it's pretty crazy looking that you can jump even 10 feet and land on your feet.
And some enemies are also super villains who can jump 100 feet across a room and crash down in the midst of your party. I've had battles where I was sure my characters were a safe distance away. I was wrong. I was horribly wrong!
