Q: If you had the one-time choice (in any MMO) to switch your class with another, retaining level and similar equipment, would you? If so, what change you would make?
For me, it would be my WoW Warrior. As much as I like Titans Grip and their tanking, I would trade him for a Paladin. They are just so much more versatile with their healing options.
In WAR, I am pretty happy with my Engineer.
