scrap the current melee sv blizz and gives us a shadow hunter spec !!! make it a complex spec, make it so that sv can be the master of multi dot, aoe and dots to drain mobs down, make explosive shot great again like in cata where you had manage your focus really well with black arrow in order to not mess it up
bm can be the cleave, bursty spec, while mm can be the master at single target and target switching.
So long as the gameplay resembles cata/mop sv, then I don't care what the theme is. Dark ranger might work if the next expansion is, as everyone seems to speculate, focused aroud the old gods/void.
