You are taking some of his DPS away put it into something like DRAGON’S ARROW from hots.
Nerfed version for overwatch
Fire a electric dragon that zags 3-6 meters then flys straight across the battlefield directly ahead only no headshot. Explodes upon hitting an enemy Hero, dealing 20 damage to the initial target and arcing into enemies close to the initial target for 3 seconds at a quarter damage. After traveling a medium distance, the damage is increased to 40. After traveling a long distance, the damage is increased to 60.
His would actually be a positive for those who want storm arrows nerfed even more as they don’t have much room to tweak his kit ATM and another ability to buff when storm arrows are nerfed again would help.
