well Starkiller doesn't have launch delay now and it's somehow used
Sunslayer has some, which got significantly reduced for 4.86
Both got some small damage upgrade (on the order of 2k).
Hope that makes them a bit more usefull, but I still think there should be a difference between them.
Starkiller being mostly for anti-fighter, while sunslayer is more like anti-bomber torp.
Their main problem as with missiles is of course lag, without any lag both missiles and torps are actually rather overpowered (those who were at the OC-Corsair eta event surely remember).
