It's a huge nerf to all the 2 dice bombers, but still a downgrade to 1 dicers because it's preferable to deal your damage in tiny packets that can't be effectively managed by defence tokens.
There are a few circumstances where it's not too bad:
*Attacking ships or squadrons with counter
*Attacking ships with salvo
*big mixed dice pools can add blues to fish for needed accuracies, or blacks for damage.
But it's still only 5 points, so if you get one or two extra damage out of it, it can be worthwhile.
