@Curty 15 dex is 9 base dmg on jishnu's. The only thing the harrier series has over gandiva is the delay for x-hit builds, which are kind of moot at 99 now.
5 more DMG than 90 gandiva, making it possibly have higher WS dmg assuming the +15 DEX doesn't overcompensate for this. Of course DoT will be lower because of higher delay and no aftermath.
