I'm a huge fan of bounded accuracy and keeping ac in a 10 to 24 ish range is great for that.
Think about this, if an ancient red dragon had a higher ac (say 28-30) what would prevent it from attacking towns, villages and even cities? Bounded accuracy makes it possible for even lower level pcs, npcs and monsters to actually do damage. Gather enough attackers and you can explain why fearsome monsters don't have the run of the realms. All good in my book.
It also works to make the pcs more vulnerable when attacked by larger numbers of lower level foes. Getting swarmed by 8 or more weak monsters could be deadly if a PC can't thin the ranks. Again, this is by design and to me it makes perfect sense.
