No Bliz isn't removing Spell crit, or are they removing +healing. Yes +crit will affect spells and +healing will be turned in to spell Power. But there will still be talents that will only affect one aspect of it such as spell crit. or like the talent for resto shaman that now only affects +healing based on Int%, and not spell power.

but in short is 5% crit worth giving up for some of the other talents now? well that's up to each person, but there is going to be reasons to not have to go in to the Resto tree now if you Elemental.
