But we also need replacements for broken mechanics -- jump as a substitute for disengage is a real problem -- if we don't use it we don't have a disengage at all. (which is strange since the goblin kids seem to have a real disengage)
Goblins actually do get disengage as a bonus action. We won't see later enemies abusing it.
What is not supposed to happen though are Bulettes being able to spam their leaping attack without provoking opportunity attacks from the party. And Minotaurs are more known for charging at a single target, not leaping shockwave AoE attacks.
