I have a question for enchancement shamans. Why do some shamans have http://www.wowhead.com/item=41531 instead of http://www.wowhead.com/item=41542. This is somewhat of a clarification because I see the shamans who have Heroic Lk killed have Flame Shock glyph but shamans who don't have Heroic Lk killed mostly have Windfury weapon Glyph instead of Flame Shock Glyph.
Thanks.
