Goliath D.Va and D.Va the Destroyer skins don’t have custom FX for her new Micro Missiles ability to fit the skins’ themes (both can be fixed by recoloring the ability’s FX to orange, however, I don’t think the missiles fit D.Va the Destroyer’s theme at all, if possible, it should shoot fireballs instead of missiles). Additionally, D.Va the Destroyer skins’ Micro Missiles is bugged, the missiles are fired from her (mech’s) feet.
(For comparison, when Tassadar received his rework with 2 brand new abilities, they both have altered FX for his different skins.)
On a side note, I think the newly added line (that shows the range of the bonus damage of her basic attack) should also be changed from blue/green to orange/fiery to fit the skins.
