I'm trying out the Thief subclass and have found that the Second Story Work feature has been altered from tabletop to just be falling damage resistance instead of letting your dex mod boost your jumping ability and I'm not entirely sure why it would be like that considering the game already puts a focus on leaping around all over the place. Come on, let me be Spring Heeled Jack without having to be a wizard of some kind first.
Second Story Work never added your Dex mod to jumping? In 5E, Second Story Work lets you climb at full speed instead of half speed. Given that climbing in BG3 doesn't take up speed and can only be done on certain specific surfaces (which I entirely understand from a programming standpoint), the change to reducing falling damage seems like a pretty good call.
