I boosted my 80 Paladin to 85 along with max AA, and created a 85 shammy on my alt account. I've since let them lapse to Silver status, and last time I logged in, most of the pally's gear was purple, most of which is due to Prestige augments. Fortunately she isn't wearing cultural armor or she'd REALLY be in trouble, but still, I'm worried that the loss of, off the top of my head, at LEAST 12 augs of 20 or greater AC, will be a serious detriment to her tanking ability.
What do you guys think? If she lost 12 20-ac augs, that's 240 AC plus heroic stats, maybe not a lot, but considering that AC augs are very important for tank classes, I'm worried she will under perform in at-level content.
