Couldn't agree with this more. Spamming fire/acid/frost/etc puddles in combat is not what DnD is about, and feels fundamentally different from the tactical team combat that DnD is known for.
And tying jump and disengage together as a bonus action is just poorly considered. It's now drastically better than the tabletop disengage and might as well be hotkeyed since you'll be spamming it nearly every turn if you have a lick of sense.
