I don't think Moira is OP necessarily, just a pain in the ass to play against like most spam heroes. Maybe a slight ult charge nerf is all she needs. Buffing Ana is a slippery slope. It's not the hero that's underpowered, it's just the current meta fucks her. She can still be powerful with the right team comps, and more-so on attack than defense. It would be cool if they gave nano boost the speed increase back, but beyblade was even worse than dive imo.
