No topic has ever gotten me into more D&D arguments than saying that a 10th level fighter should be able to fall off an airship, hit the ground and not immediately splat, but rather limp away from it after tanking the 20d6 damage.
I want a squad of Dwarven Fighters to be able to leap off of the same airship and do a three-point landing, because what the hell would Dwarves need parachutes for?!
Evasion reduces dex save effects to half damage on a failure, and no damage on a success. The rogue and the monk can dodge the comet completely.
