It's actually the other way around. You yourself have apparently leveled a Drk but you clearly haven't mastered it yet since you're saying you should never have Dark Side off and you're complaining about the MP cost to turn on Grit. There are times, when you're trying to fill your mp bar back up to full super quick, when you SHOULD turn off Dark Side. By turning off Dark Side + Grit and Using blood weapon (and shadow wall should you need to soak damage) you'll recover your MP back up to full within half the time it takes for blood weapon to be fully used up. Once it's back up to full, you can toggle DS back on, use a high MP draining DA combo, turn DA back off, finish topping off your MP (which will happen just before blood weapon expires) then hop back into Grit and turn back on DS. Is this a complicated move? Sure. Is it complicated for me? No. Why? Because I don't use a controller, I assign every ability I have to my keyboard, and I've practiced and gotten used to how to easily refill my MP back up to fill with ease while not having to sacrifice any DPS. And ever since the expansion's launch, the only time a Warrior has surpassed me in DPS while we were both tanking is when they spike their dps with their offensive buffs/fell cleave/etc but once the spike ends their dps just goes back down and I surpass them again within seconds. Just practice more with Drk and stop being so biased because every time you compare the two you list off everything that a War can do in depth but hardly touch on anything (if at all) that the Drk can do. It's YOU that's not giving Drk the credit deserves because you're spoiled with an easier rotation with Warrior. It's the same song and dance that it was when 2.0 came out. People complained that Warrior wasn't nearly as good as the Pld or couldn't do as much damage as a Pld because people weren't used to it yet.
