Well, actually Warrior is surprisingly tough, compared to what I read about them in this forum. Granted, you need top equipment for them, and Paladin/Dread Knight is definitely even tougher for sure. But - thats it. With a full Qalian Armor, a lot of Boon of Health, and a lifetap
on your greatsword (or maybe even better two qalian weapons in dualwield ?), even a Warrior shouldnt be too bad solo.
