I think it will just feed even more in to the exact same stereotype legion shadow has.....great for bgs/large scale, struggles against melee in arena. This will now lead to people holding kicks for void eruption so they can prevent void shield --> void bolt heals. It's a survivability nerf and a damage buff pvp wise. Shadow keeps getting better and better for RBGs/BGs and worse and worse against melee. If shadow can find a comp that can keep it alive, the rot cleave will be intense though. I just doubt we ever get away from the melee train though.
