Not a fan of having an arrow that either goes though a wall or shields.
Personally I think hanzo is kinda a BS hero in overwatch, along with Widow in that they can instakill alot of the cast from range with no counterplay apart from other very long range heroes. Couple that with some badly designed areas in maps with very long sightlines and you have a recipe for no fun for anyone who’s not said snipers.
I wasn’t a fan of the sniper in TF2 either, until he got the huntsman bow which I loved, it was similar to hanzo in that you could learn to easily nail lower powered headshots and kill characters, but the arrows not being as fast as hanzo made him more mid ranged and had to get in the fight more. (Was still maybe slightly broken tho) Also the TF2 sniper was fragile, didn’t have mobility like hanzo or a powerful close range ability like storm arrow. Imo a character that powerful at range should be weak up close or he has no downsides.
I would lower his fire rate and arrow speed a bit, give him a dagger he can use on a cooldown so he either dodges away or gets the target low with an arrow shot and has to commit to kill with the dagger.
