The big thing that the mythic rules break is the action economy. Other than dual initiative there aren't the same mechanics on the monster side to balance that out so you need to pad out encounters with additional mooks just to give the players something to do, or increase the HP of the bad guys by a factor of 2 or 3. Many of the encounters in the 4th-6th books were over in one round, even with HP maxed.
