Tanking can be intimidating sometimes. I usually tank in all MMOs I play and it can be quite stressful. Granted I haven't really healed much, but I'm always grateful to a good healer, they are my lifeline. DPS does need to make sure they deal damage quickly so the encounter can be over quicker and the tank doesn't take too much damage. We all play our parts in the battle and if any part of a light party dies, you do can feel the strain. That being said, it does feel like a lot is expected of a tank. You kind of become default party leader as you dictate the order of battle, or at least try. You have to keep a keen eye on the entire battlefield and ensure you get the right mobs, know which mobs to ignore, etc. To the point that walkthroughs feel mandatory for even a first pass. I haven't really gotten farther as any other role, but I do wonder do DPS and Healers feel the same way in their progression through the game?
