Here's another way of looking at it. Say you have a BP with 500ac and a bonus of 1% mitigation bonus. Then you have another BP with 600ac. Both individually mitigate the same. However, the 1% will be added to your total mitigation number, so in the end a BP with 500ac and 1% mitigation does more for you than a 600ac BP. Therefore, to a degree % mitigation boosts are greater than pure armor rating.
Then there are shields. Shields say %block vs level X mob. So a shield block % will scale vs the mob your fighting. A level 40 28% shield is the same as a level 48 20% shield (Both are roughly 20% vs a level 48 mob). It's only at level 49, if you get a LvL 49 20% block shield that it will outperform a level 40 28% block shield. Since it will block 20% against a LvL 49 mob, while the 40 shield will block 19% instead. This concerns blocking only, as the armor rating can also be an influencing factor, and if the shield has a % mitigation on it as well.
The effect of armor class raising seems small compared to the % boosts. Although, yes you still need a base armor class for the % to work on, once you have two tanks with similar base ac, the % boost is what makes a bigger difference.
