I don't know if there will be any changes to falling damage in the beta but I hope so.
Tonight our group (12th level) were considering jumping off a 450' cliff. Everyone laughed at the idea, but knew it would work. They all have good fort saves for massive damage and plenty of hit points for the 20d6 falling damage.
I've always hated the relatively minor damage from falling and came up with a quick rule tonight: Fort save or die, with the DC equalling the height/10. In this case a Fort save DC of 45.
What do you think? A 200 foot drop at DC 20 doesn't seem too bad, maybe even a little weak, but it would make the players think before they jump.
And maybe lessen the save required with an Acrobatics check, something like -1 to the save DC per 5 or 10 on the Acrobatics check.
Enough rambling, time to get some z's.
