We're planning to shrink the min range on ranged attacks to reduce or eliminate the "dead zone". The only point to the dead zone was to ensure the min range on ranged weapons was enough such that ranged weapon attacks wouldn't be used while also being melee'd (at least by mobs... players have a bit of slush built in).
Mortal Strike effect to aimed shot
2.3 will be up on the PTR for quite some time. Several classes are likely to get more changes before 2.3 goes live, it's just a question of which changes (ie: we're still considering the mortal strike effect for aimed shot for hunters, among other possibilities).
