Why nerf doom? he's one of the most underpreforming tanks in my experience.
Why buff ana? She's already picked extremely often in my experience up to diamond. She does solid healing and the grenade is disgustingly strong. This feels unncessary.
Wowhead posts has a typo saying they reduced the CD of Rocket Punch when it was increased to 4 in the official blue post. Doom is also now worse than before the buffs with this Rocket Punch nerf. People underestimate how huge an entire second is for your major ability. It was also won't fix whatever they're trying to do with him. imo would've let him sit for a few more weeks and let people get used to playing against him. Then look at balancing.
