There is also a level delta component for Tenacity vs Potency checks so it is significantly easier to get debuffs from higher level enemies and significantly harder to inflict debuffs on higher level enemies.

I was hoping someone would point this out. A level 80 has a better chance than a level 75 of sticking something on a level 89 elite. The ability/gear this is clearly written, but this is overlooked a lot.
