Whoever said you should aim for front accuracy @690+ is wasting 50-60 crit.

Ask yourself how often you are raiding where you stand in front of the boss or adds. Then ask yourself how long those periods are and if you can move or if ur planted. Then ask yourself why you don't have 50-60 more crit.

650-660 acc doesn't mean you instantly miss every attack at the enemy's front. It's like 95%, give or take. Probably a bit higher. So you give up 50-60 crit across the board to have perfect accuracy 10% of any given fight and 50 useless stats the other 90%.
