The TC quite obviously has a valid point which many people are either choosing to ignore, or it simply lies beyond their comprehension.
For me, this isn't about shaman vs another class at heals, or even about shaman vs shaman. IMO for any given resto shammy, the totems are simply not balanced well.
I appreciate that totems provide different buffs depending on the situation, and that a player has to use their intelligence to decide which to use - which is fine. The problem is that an intelligent player will (nearly?) always pick HST over MST because of the difference in power/benefit.
