Yeah. Didn't know that there was anyone with that much tolerance for that crap. That forum (Battle net OW) has also shown me that D.Va mains are the worst :s
I think you meant to say Gonjo mains. :^)
Though D.Va mains kind of do have a reason to actually be pissed, as well as the people who know why D.Va was picked the most next to Reinhardt. She was picked to counter Soldier76, since now he is too good. The best DPS. The triple tank meta exists because he can solo DPS. D.Va's matrix can cut down his Ult, but then she'd take bullets to the face and almost die. It was important for her to be that bulky because Soldier76's higher damage means he gets his Ult even faster than before... And he already got it at a very fast pace (he may as well be the Mercy of Offense in terms of how fast he gets his Ult).
D.Va was garbage. With garbage everything.
So she got a rework and everyone complained because she became kind of viable again.
She got nerfed. People were like oh OK.
She got buffed because they realized she was still garbage after the rework anyway.
People were like "oh no now she's 100% viable like Reinhardt it's OK if it's Reinhardt but not D.Va omgomgomg!"
So they nerfed her just a bit too much (+100 HP/-100 armor would've made more sense since her critbox is impossible to miss).
TBH they should've tried giving her pilot form 125HP and less damage from her gun. Getting her out of mech was never hard unless she was being focus healed, keeping her out of her mech was hard since she could still be a threat and would get Ult-charge super quick. Also when she was out of her mech, she wasn't exactly useless to her team like she should be. Even though her damage isn't high it's still enough to contribute to a fight and win/stay alive.
Big blob of text aside, D.Va's nerfs are not TOO bad. In fact her gun is nicer than before, despite the minuscule DPS nerf. Her damage is now even better on smaller targets, but not as good on big targets. It's just Soldier76 has been indirectly buffed because of her weird nerf, and he was already dangerously teetering towards the OP side. His only hard counter is now a soft-counter at best. But Rein is also a soft-counter, and he is actually 100% viable so... Whoops.
