Lvl 30 DPS Shaman Hitting 140,000+ In Healing

I was really worried that my DPS spec'ed Shaman might have some problems healing at the higher levels, but as you can see here that is not an issue:

70k healing in Tor Anroc: (Of course I got out healed by a Zealot)



When hitting tier 4 I did over 140,000 healing: (And we still lost...) (Also notice the 240k healing Zealot - WOW!)



To make sure I just did not get "lucky" I went ahead and knocked over 140k again:?
