my shammies are wearing a few epics from wintersgrasp and pieces bought with honor, the wg gear has a good amount of +hit and there's nice shoulders, pendants and rings for honor - combine those with AH gear & weps and you should be ok. I recommend farming HDTK for the pants for shammies - my shammies do well in heroics with this gear because of massive +stam although I do suffer occasionaly from mana issues but nothing a mana pot doesn't fix
