well, its actually quite good. especially since a rogue will then only do like 20's on you when you do get hit.
its definately a skill that you can do without though, but it is a good skill when you have the spare points, or if you sacrifice some from other skills. the only skills worth maxing is meditation in the mage class anyways(if your going wizard), the attack skills are just optional to max and only speed up the grind. they will later be replaced.
