For wrists, there are the 219 epic boe items from Uld http://www.wowhead.com/?items=4&filt...=3;crs=1;crv=0. Not all specs are covered though, so YMMV. If you are filthy rich, ilvl 245 craftables from crusader obrs will hit the market at some point.

For shoulders your only option is to grind the heroic daily to buy T9. Personally, I rather detest the alliance shammy T9 gfx, so I will just have to stomach the 60 emblem cost for T7.

For back, your dps casters should be wearing the Deathchill Cloak and liking it, its more dps than anything you can buy from conquest and downwards anyway
