I won't speak for Armor, but the OP statements he quoted came from what I always put in my slider threads.
Here's the thing, saying something is "easy" or "hard" does NOTHING for us to help you. Running is "easy" for you...why?
- too many broken tackles?
- line holding blocks too well?
- line getting upfield too quickly making it too easy to get to the second level?
- blockers get to the outside too quickly, allowing you to constantly get to the edge?
- defenders do not react quickly enough?
- not enough defensive penetration?
- pursuit is not sufficient?
I can go on and on and on. The point is....all of those things point to completely different adjustments. You could point out something that Armor (or others) have seen....every one goes..."Yeah, I've seen that too" and that can help point to a quick fix. Saying, "it's too easy" without anything else just comes across as being whiny (whether it was your intent or not).
