[jumping is a part of the TES series and is a habit you have acquired if you played older TES games prior to Skyrim for acrobatic skills
play pvp with kangaroos in front of a player who just jumps and tell me if it's fun to face such a gameplay...
Otherwise, I didn't say that "jumping" shouldn't exist anymore, but should just consume a resource in the same way that "dodging" consumes a resource is just logic !
