Keeping people capped not just when they take enough dmg to use a cure 6 helps too. Cure 4 aslong as you not spaming it is enough to top off someone with out wasting your oh sh*t timers on cure 5 and 6. Knowing when and what spell to use is just as important as not lossing target. Really there more then 2 cure spells in the game whm can use.
