It feels really bad to die as D.Va while your mech is exploding. If it gets killed, sure - you got outplayed. But if you charge your bomb, use it at a really good time and place then die before you can remech because a KT clicks you or something, it really sucks and feels unfair - like you are punished for using your inbuilt survivability.
Just buff her so that she gets 50 armor while the mech explodes. This wouldn’t affect winrate much, just stop those really sucky situations where you feel punished unfairly.
