Elite Monsters and Elite Bosses

Is it just me, or does the level restriction on spawning Elites apply to 150+? I was grinding at SDH on my 209 I/L for about an hour for the butterfly event and didn't see a single one.

And if that's the case, then anyone over 218? can't get their own Elite Mobs/Bosses.

Seeing all the people yelling at me for attacking at KSH while I was under level 190, I learned that once you get 20 levels or higher over the mobs, you can't spawn elites in that map. So yes, anyone over 218 probably can't spawn their own, even at WG.
