If you don't pre-buff you're simply being lazy no two ways about it. You claim you play your job seriously and effectively, obviously not if you're not doing this, stoneskin and adlo can be the equivalent of up to an extra 4k HP on a WAR before they pull. That's enough time for you to cleric's stance get all your DoT's and shadowflare up before you even have to worry about curing at no cost other than you having to press buttons.
