This text is false as a bonus on to-hit will never give you an additional critical hit as crits cant be fully resisted. 20% crit and 17% resist give 63% normal hits. Plus one percent to hit means 20% crit 16% resist and 64% hit. crit goes 21% crit 17% resist 63% normal spellhits. For a frost mage that gives the same damage bonus. As you easily waste damage on "normal" mobs with lvl 62 when hitting the 2hit cap (99% afaik) I strongly recommend to go for crit stuff once you have some 2hit items.
