As the title suggests how many Resto spells on your bar are needed to get the job done at Veteran levels. I've healed at <50 and honestly I think you could get away with 1 burst heal and 1 burst over time. If you have the magicka to heal when needed that all you need. The reason I ask is that I'd like to run a full light armor set with Pets and a Ward spell for the pets and myself also on the destruction bar I'd put power surge and daedric prey(for boss units). Second bar Could be Heal, HOT, Shield or Ward, Pet (either one), Pet (magicka regen 10%).
Do you think that would work for PvE? I wouldn't recast any pet but I would start fights with power surge, switch to resto and then focus on heals and positioning.
