I concur. Focus on the XP aspect of it over trying to down bosses in the early phase of your leveling. Alternatively, you could dual box quests with your tank and healer to 70 which will give you a serious leg up for leveling your DPS.

MC can be a serious problem that (mostly) comes down to luck of the draw and your teams gear and thus survivability.

For the 2nd boss of Ramps I don't even bother with tanking it due to the knock back and let my casters do that. With shamans I use grounding totems to take basically no damage. My tank thus just picks up the felstalkers.
