One cool thing about the monster design is that you could start with say an Ogre and have him be a solo for low level players, then a few level later they show up as a pair and they're just Elite Brutes now, the na few level are they're regular Brutes under a powerful leader and then later you can mow them down in the Epic level as minions.Yet another thing 4e got right - mooks. I realize some people hated them - but they could really add dimension to combats.
I've used them for 5e and they work well in it too.
Sorry, I get that's not what your post is addressing but that's where my mind went reading it.
And despite the fact you can knock them down, they can STILL threaten to take HP away from you and box you in with their number.
It means that the same creature is available at different levels of play and you can feel your character get better at facing the same dangerous critter. It also gives you perspective on the people ordering those guys around. "Man, this guy got OGRES as underling?! Remember how hard we fought the first time we met one of these guys? He's probably not to be underestimated."
