Honestly, this seems like an issue on the low levels, because AC is pretty frontloaded. It is not rare to have 1st level characters with shield being in the 16-18 AC range, but after this initial surge, it doesn't scale extremely well. So in the first tier, yes you will have issues hitting with the low bonuses, but around the level 10, you are hitting with 4-6 on your dice again.
