Armor does not have diminishing returns in the way you are thinking. Going from 10000 armor to 11000 gives you exactly the same increase in time to live as going from 30000 armor to 31000 armor.
In fact, the more armor you have, the more useful it becomes. You should be at the armor cap as a feral druid tank. If someone tells you armor becomes less useful because of diminishing returns, they are wrong. Armor only becomes useless if it surpasses the armor cap.

Ah, I see your point, thanks for straightening out the silly ramblings of a non-math guy. It hadn't fully clicked that the damage mitigation chart had a curved line (indicating diminishing returns) and the time-alive chart had a straight line, showing NON-diminishing returns.
Since how long you'll live is ultimately the only thing that matters, the 'diminishingness' of the returns in terms of damage mitigation is a moot point.
I'll go get back to maxing out my armor now.
