Even with the incomming shaman buffs i realy dont see how a resto shaman can compete with a disc priest.

Even with the new change to earth shield there is still a easy counter to it, just attack another target. Put a rogue on your shaman and he cant do much healing, no he wont die but you wont recive heals apart from riptide and ns/healing wave.

You get 1 hex and 1 grounding totem but you lose blessing of kings,hand of protection,divine sacrifice,hand of sacrifice,aura mastery or PW:shield,PW:fort,spitit buff(not much help but trash buffs are great since it takes time to dispell them),Shadow resisitance buff(same as last taken into account that there are few shadow spells around in 5v5 atm) aoe fear,pain supression.
