Let me just start off by saying the new way to get reputation is really amazing.  This is one of the best things blizzard has done in wrath of the lich king.  Being able to put on what ever tabard you need to gain reputation with and go do ANY level 80 dungeon is so great.  For instance last night heroic halls of stone full clear.  I hit revered with wyrmrest accord but the others in the group were all grinding a different reputation.  There is no more of running steam vaults over and over and over just to get reputation.   This is a wonderfull change and i think will keep me running more dungeons than I ever did before since i dont have to find a group for a specific dungeon.

As of right now I feel really good about my shaman.  I have cleared what people call the hardest heroic in the game.  I still want to run every heroic not for gear but for reputation.
