Hanzo is only seeing one change in Overwatch 2 (other than his visual update), and that's the reduction of the damage of his non-headshot Storm Arrows from 70 to 65. This overall nerf to his burst damage is likely due to the five versus five format of Overwatch Two, as there will be one less tank on each team for heroes to hide behind, making it easier for Hanzo to deal damage. Aside from this, Hanzo will play the same way in Overwatch Two as he does in Overwatch.
