Running into a simple band of orcs shouldn't faze a high-level party, but encountering a large throng of orcs outside a demon lord's citadel might. As the PCs increase in level, the way in which they encounter perennial threats like orcs or goblins should change.
For high-level parties, these monsters will occupy the same role as minions do in 4e. I predict that the minion as a specific creature type will be gone in DDN.
