For all casters in a 5s team. Our setup always includes 2 healers and a mage. Trying to figure out if it is more beneficial to have 3 spellsurges on the team or if the spell damage/+healing is better.

From a lot of the videos I have seen and the matches I have been a part of, it seems that mana is always an issue in the end.

I know that it wouldn't beneficial for 2s or 3s, but I am trying to see about 5s primarily.
