If your SK is a twink, forget these and get SCHW.
If you have the money to buy SCHW, get those and forget these.
The AC is nice, but by the time an SK is an appropriate level to have ally Coldain faction (I believe that's what you need), you can probably afford better. As I've made clear above, SCHW are superior... 5 less AC, yes, which is something to think about as a tank class... but the haste and stats make up for it. I would reccomend letting another plate class loot the corroded gauntlets. These really aren't worth it for SKs.
On a side note... for the SKs that have gotten this, what color are they? Curious minds want to know.
