Given the Mortal Shots bonus, isn't it always better to go for crit rather than hit? You gain more from a crit (+130%) than you lose from a miss (-100%). I don't see why it is particularly necessary to max out hit. For example, if I have a 100% hit chance and 15% crit chance, I would on average do 119.5% of normal damage (0.15*230% + 0.85*100%). If I traded 5% hit for 5% crit (95% hit chance and 20% crit chance), I would expect to do 121% of normal damage (0.20*230% + 0.75*100% + 0.05*0%).
