I thought this was pretty nice plate. Personally I hate added vulnerabilities, but that's not really on the basis of empirical evidence. The resistance won't help/hurt the price much. You'd be better off with warrior slash protection, but that's a maintenance issue, and there are those who hate maintenance issues as much as I hate vulnerabilities. The big plusses for this armor are a decent enchant, crit padding, and T5. It's also a nice set of armor to continue working on.
I don't use Lich. If you want to do business with me, contact me via PM, IG, or on AIM. Or maybe use smoke signals. Don't like it, get off of my lawn.
