I just used my new carrier in some elite STFs and now I am wondering about the right pet layout. So far the Peregrine Fighters are winning in my humble opinion, but I would like a little bit more input, before I go and invest some hard earned dilithium.
What kind of pet? Siphon Drones! But wait, there are non for the Fed carrier.
For STFs Peregrines seem to add the most damage and it looks like you can't do much wrong with them.
2nd place for me are Runabouts with their Tractor Beams and high HP numbers.
Type 8 / 10 shuttles and Delta Flyers look somewhat underwhelming to me but I only tested the standard Deltas with Tachyon Beam I. Stalker Fighters with an aux disabling ability are, well, not very useful in STFs and I guess at best situational in other scenarios.
For me KDF pets still have the advantage, not only because of the Siphon Drones, but also because they are more straight forward. They only serve a single purpose (damage, power drain, shield drain) and thus really shine in their speciality. Fed pets look just like a not so successful attempt of "OMG we need more variety here".
I did see the Tachyon Beam, but I do not know, how much it drains the shield of the target. In Elite STFs it is not that much against anything bigger than probes. As I stated above, the Stalkers did not enough damage and died anyway, Deltas are nice, but Pegerines did way more damage.
