Higher level characters ONLY fight orcs

[Gryph]

It seems to me that a flatter power scale just means more variety. If you want your campaign to move away from regular humanoids then you can. If you want humanoids to be the focus of a long campaign then you can have that too. It's a win-win.

Damage and hit points can handle scaling just fine. Unlimited numbers of anything being ineffective just kills immersion. Even the topmost level adventurer in the world should be concerned about facing 1000 orcs.

D*** right.

"No S*** there we were 10 against 1000. Was I scared? You bet I was scared. Those were 10 of the baddest MFers I every fought."
