I use regular beam arrays with BFAW on my Delta flyer also I have the Tetryon Plasma engine from the Cstore Yellowstone runabout with ejects a tetryon plasma cloud slowing the fighters I can target the walkers, but also take out the fighters. I run a perfect ran the other day with only 4 people (one yahoo, tuck tail and left us)
Oh by the way BFAW does not work on the 360 S-type beam arrays also the 180 wide angle quantum torp is great but my rommie cant get it cause it comes from the tier 5 Assault Cruiser and Romulans dont get access to their allies tier 5 ships.
1 stay with your squadron alone you are toast
2 it is possible to approach unseen try and do so
3 point defence /bfaw/ts/cannon skills are useful.
4 hug the water when approaching walkers they have a "blind spot" to low level attack
this does NOT help with the shuttles
5 keep team chat on at all times and Communicate
6 if someone cuts and runs make a note of who and if you see them at the start of another mission LEAVE
It gets easier the more people you have with point-defense and if those people are able to time them right. I've had one group where 3 people just kept wasting their cooldowns on the same group of fighters. Other than that, slows (e.g. Theta Radiation, Graviton Pulse etc..) work wonders on those fighters.
In addition, you want anything with [acc]. The new space trait from the latest lockbox (Precise) also helps quite a bit.
