Taking a typical Amdapor Keep or Wanderer's Palace where you fight 1 pull at a time, Scholar can more or less keep Cleric up full time. And I should damn well hope it makes a difference in kill speed; 75%+ of tanks fail to maintain hate when I go full AoE DoT crazy (Relic+1 ~400+ MND, varies due to spiritbinding accessories). WHM is not that different, and I agree with Tanaya 101%.

If you don't stance dance DPS (out of spite/indifference, not out of fear), you're purposefully limiting yourself. There are lulls in almost every boss fight (or in some cases, the lulls are just dodging AoE on non-tanks so whether or not it's a free pass depends on if your DPS are awake and dodging). If you're new, just ease into it as others have said. Try to youtube a healer PoV run of (non-speedrun) AK or WP just to get an idea of when/what they do in those "lulls". That's how I changed from a robot healer to what I am now.
