Just today I went into battle against 3 Carriers and one Carrier Escort and pets flew everywhere. me and a fleetmate just used FAW with our buffs and pretty much one hit all the pets, we killed them all but 4 or 5 total from the pet spammers.
Tractor Beam Range is 5km, PSW 3km. So ... if you're lucky, yes.
Runabouts are like lemmings, or suicide bombers... I swear they are probably going "lullululuuluuuululuu JIHAD!" as they orbit around 2k or so from there targets.
I think this mostly has to do with the AI, which with the changes to siphon drones (which effected alot of different pets) they are alot more likely to just stay close to something thats stationary/slow. Meaning runabouts slowing stuff generally means they want to hull hump it or something.
In other words PSW can work, its just normally more a matter of them being on the right Z-axis as opposed to being close enough.
I might try some of these ideas here like running an extra APO or PH, these danubes are driving me crazy so now i guess its worth giving up a HE or TSS for PH or giving up an extra CRF for an extra APO.
All I been doing right now to counter danubes with my defiant is to to always target the danube user with my decloaking alpha strike, they usually cant survive very long if u hit Alpha3, go down fighting, Tac fleet, APO, TT, before decloaking, then firing CRF3 and THY3. I do have trouble with them and get tractored when go down fighting and Alpha3 are on cooldown though because my Alpha wont always take them out so need more ways to break the tractor afterwards.
