Mutas Bounce Goes from 33% DMG to 40% Damage - would it he OP?

Mutas seen to have a real but highly niche role in all match ups. Maybe a touch more for ZvZ.

I remember them being a menace in WoL and really encouraging a dynamic and longer mid game.

If their damage fall off was a bit less it shouldn't effect their base damage, but they would scale a bit better with flyer upgrades.

Thoughts?
