D.Va isn't awful but I think she's a little weak right now. They shouldn't have so drastically changed her at once 2 times in a row. Both her nerf and buff were not well done.
The buff wasn't executed in a smart way. The only real problem I think 100 hp 400 armor dva had was her extremely slow move rate while firing which meant most targets could simply run away. Evidently Blizzard felt similarly since they buffed that (as they should) but also gave her 100 extra hp no one actually asked for which made her a little too powerful. On top of that, her main competition and counter (Zarya) getting nerfed, a soft counter to her (Mei) getting nerfed, and a couple heroes she counters (Soldier, Torb) getting buffed all turned her from a D tier hero almost exclusively used for stalling into one of the best heroes in the game. Furthermore, Ana heals combined with D.Va's already excessive amount of bulk made her seem immortal and unpunishable. They needed to not change so much at once. They clearly wanted to make D.va good but this was not the way to do it. I think if she was just left with the 100 hp 400 armor but was given the movement speed while firing buff she would have been balanced, but c'est la vie.
I don't understand why they thought the damage change was necessary (apparently for "consistency" even though she was never that inconsistent if you were tracking well) but it was fine before and now she's significantly weaker against armored targets or after her damage starts to fall off. Not the end of the world but I always felt this was unnecessary and dumb.
The armor nerf was really not well thought out on the developers part. They wanted her to feel more mortal but they decided the 400 armor (which she had ALWAYS had since release) was the issue when in reality it was giving her 100 extra hp. With the removal of her armor she actually fares worse against several targets (tracer, roadhog, soldier, reaper, lucio, etc) than she did before with 100/400. While its not that much worse for some of them, the extra 100 hp also means she feeds more while taking damage, as opposed to when she had 100/400 and the armor absorbed that 100 and a bit more too (at least against most relevant things). They should have knocked off the extra 100 hp or tried 300 hp 300 armor first. Removing 200 armor was just too drastic of a change imo, they overreacted.
She can do lots of things honestly. She could dive a lot more back then when she was overpowered but she can still do it now sometimes, she just has to be a lot more careful. A fair bit of her play time is dm botting too. I think shes in a pretty good spot just roadhog is so good and he totally fucks her over and prevents her from making any sort of play if he's in the equation, since its an easy hook and he almost 1 shot demechs you. I would say his presence forces dva to play a little too conservatively, to where she really does feel like a dm bot sometimes. Getting some armor back would help to fix that, as would nerfing roadhog. Even without roadhog though, she cant dive certain targets like she used to due to her severely reduced armor. Torb wins the 1v1 now if he has turret up, for example, and tracer actually severely damages her now.
