Fine. You win. The whole "sets your speed to 30 feet" is still pretty useless now that all PC species have a base speed of 30 feet anyway.In 2014 you basically needed to dash in order to get something out of the jump and then its main usefulness is dealing with exploration which becomes less important as the party levels up.
The new version essentially increases your move speed to 50' which is very good in combat.
And now for something completely different: Madness is still in the DMG, but it's been renamed Mental Stress and has been greatly simplified. Mostly it deals psychic damage, but you can still do short-term, long-term, or indefinite effects. Instead of the nifty tables to roll on, short-term just imposes the Frightened, Incapacitated, or Stunned condition for 1d10 minutes, while long-term imposes Disadvantage on "some or all" ability checks for 1d10 x 10 hours, and indefinite is just a long-term effect that lasts until removed by the Greater Restoration spell.
