Since Jumping is confirmed, can we fall off a cliff, take damage, etc?

Our interview at Japan expo

Thank you for posting this interview, I've never seen that before.

Doesn't make sense.

I agree, I feel that by having invisible walls everywhere, it's more unrealistic and more immersion-breaking. For example, outside Uldah area, the cliff that has a sloping path going down, I should be able to just jump that.
