You typically want to stack a few healing over time skills together ahead of time. Grand healing, for example, is an AOE heal over time. A skill can fall into multiple categories.
To be a bit more specific, there are AOE heals, Heals over Time, and Burst heals. At the baseline, you need healing skills (duh). Originally posted by :Hm are there some must have things i shud use? I mean, in a broad sense yes.
