I don’t think its controversial to say, D.VA is pretty strong at the moment, having back to back buffs for I believe that last 3 patches. Most recently a buff to her micro missiles and DM.
I also don’t think its a stretch to say that her DM is really REALLY strong at the moment. If you team isn’t running beams it is INCREDIBLY hard to actually beat a competent D.VA. She eat’s sleep, she eats anti, she eats ults like nothing, even when she shouldn’t due to its range. You can’t even really wait for it because by the time you chip away all her armor, her DM is back up and what damage you did will be healed by supports.
I’ve heard people say they should tweak the duration of DM in correlation to how much she eats stuff. The more things she eats, the longer its duration. Kind of like Zarya bubble, rewarding you for not shooting into it.
