I am feeling confident with my healer, so now I am working on establishing my Tank. I decided on aiming for Paladin. All of the guides I am reading, however, suggest Mercy Stroke as a cross coass skill. Reading about the skill, it seems VERY situational and I would rather not level Marauder to the high 20's. Is there an important use for Mercy Stroke for a Paladin or may I skip in for something else?
