It looks like shamans, priests, paladins, and druids are all losing their efficient heal (Heal, Healing wave, Nourish, and Holy Light) and big heal (Greater Heal, Greater Healing Wave, and Divine Light) unless they are specced into the healing tree. Druids actually get Rejuv and Healing Touch regardless of spec, since they don't really have a "flash heal" (Regrowth is Resto Only)
This causes some issues, since for instance, Healing Surge as enhance/elemental with decent gear at 85 heals for about 9k, while flash heal as shadow or flash of light as ret heal for upwards of 15-17k (or ret word of glory in the 20k range). The current Resto shaman tree is designed to compensate for the crappiness of Healing Surge with purification giving +25%, Nature's Blessing a further 18%, and tidal waves 30% crit (all of which leave the spell sorely lacking and only really useful for building stacks on Baleroc).
Furthermore, Enhance will be losing the ability to use Maelstrom Weapon on greater healing waves, which is a pretty huge hit to survivability.
Currently, the access for shaman offspecs to Greater Healing Wave lets them spend a lengthy period of time after a fight casting a medium efficiency large heal before moving on to the next target, or in enhance's case, sacrifice a fair chunk of damage for a decent heal. The lack of spell pushback or cast time reduction makes the spell not really viable for use during combat unless used with maelstrom, but at least heals for roughly 15-20% of your max HP per cast. Trying to heal up with Healing Surge will be pretty awful, since it costs 1k less mana and heals for half of GHW.
Neither spec right now is very good at offhealing (as elemental was decent-ish during WotLK), considering how strong flash heal/PWS are for shadow priests or Word of Glory for rets.
Basically, please don't hose elemental/enhance survivability for resto's sake, which has pretty much been done all throughout cataclysm. I see some of the silly survivability and self healing abilities being given to non-healing classes like rogues, warriors, DKs, warlocks, hunters, etc, and can only really shake my head.
