I want to see an Ana buff that reloads her and her target’s ammo when she pops her Nano Boost.
This would help Nano Boost be used more reactively and make sure that Ana has enough ammo to support her Nano Boosted teammate and that her teammate won’t be wasting precious Nano Boost time by reloading too soon. This would help her make the most of her ultimate. It’d be small, but at least her ultimate would finally provide some benefit to Ana (she’s the only hero who doesn’t have any kind of self-buff on her ultimate). It would also help her ultimate feel less overshadowed by Valkyrie and Supercharger. It needs something extra to set it further apart in my opinion.
And if she still needs a buff after that, I’d argue for an increased Nano Boost duration (10 seconds seems fair) or a cooldown reset component tied to her ultimate as well.
