If you want to look me up on the armory, I'm Ruzhyo on Norgannon.
I'm coming up on the points needed to get my next piece of valor gear, and I'm giving a good hard look at the leggings. My last three upgrades lost me about 250 hit rating, and recovering from that has been pretty harsh. The ret T11 legs give hit and mastery, and the T11 prot legs give dodge and parry. If I'm honest, I really couldn't care about the set bonuses, they're garbage, so ignoring those it seems like the ret legs are the way to go. I get to keep my precious hit rating, and I get more of a better defensive stat. The only thing that sucks is I lose about 40 strength, because for some reason the prot legs have way more Str.
Also, doesn't it seem like the prot set bonuses would be better for ret?
