I disagree.
With the 30% free cast speed added to DS, energy is not a problem. I can drop to 0 energy and get it all back (with stim and DS spam) in about 8 seconds. As far as an oh***** button, we don't get one in the usual sense, but the changes to Nanotech make it amazing for getting a fast 6k AoE HoT off. Surgical probe will always be strong, and that got indirectly buffed with an increase in the number of active combo-points up.
I think overall, with Sorcs and BHs getting a few nerfs and mostly buffs for Ops it's defiantly looking like we are going to be the preferred rated WZ healer.
