I think Decimators will be good because their anti-ship is so lethal that enemy squads are going to want to attack them, mitigating heavy. 3 of them are throwing 9 blue dice, throw in Rhymer, Boba and Dengar and that's 10 blue 3 black, more than enough to erase a small ship or seriously cripple a larger one.
Decimators don't require squad commands and don't benefit from bomber command center, this frees up a lot of points are normally required to make Tie bombers work. The fact they have counter is also huge, it significantly ups their anti-squad damage.
Edit: Best for Last. I can drop all those gozantis, and other junk I was using to make Tie bombers and their escorts work and invest those points in real ships.
I'd agree if Decimators had bomber. 1.5 Damage isn't really that worrysome.
