There's good and bad to this. Under the current system, if a melee wants to maximize their dps they have to lock target, else autoattacks cease when they are shifting from flank to rear. Locking target makes dodging aoes or noticing what's going on on the battlefield outside of close proximity to the boss (such as adds popping) difficult. So, on this front the adjustment is a positive. The negative, of course, is the whole untarget/sheath/turn away thing for dodging stuff like gaze attacks and blighted bouquet. Is this really an issue though? At the point in the game where these attacks exist, brds and mchs do not autoattack, and thus ranged players can just turn around like we've always done. Melee players need to take a step or two away from the mob and do nothing. Getting out of autoattack range is only a couple steps. There's no reason to drop target and sheath. And since these players will no longer be playing with a target lock executing this maneuver is just as fast as the unlock and turn movement we're accustomed to. In the end, this is a "wait and see" situation. This has all been rather poorly described, so we're gonna have to see it in action before we can make some definitive judgments on whether it's a good or bad thing.
