So i decided this week, with all the rotting TOV raid loot happening, to outfit my box bard. I was able to get 17 pieces of raid gear, which significantly improved the stats on my bard. One such stat was the first number of AC, which increased from 5910 to 7071. However the second number after the slash barely moved; IIRC it went from something like 1139 to 1174 or so (I am at work and don't remember specifics, I just know it barely went up). So the question is... what makes that second number go up? Items, clickies, augments, buffs, etc. Thanks!
