tractor beam to hold stuff in front being a cannon build, can be swapped, aceton beam 3 to reduce incoming damage. x2 HE to get rid of shield drains from borg and the occasional plasma fire with small resist and heal.
x2 TT because quite simply nothings better especially combined with RSP
you can cycle through all the heals, shield and hull and stay alive especially with the huge HP sink the bort has, combination of shield and hull tanking. BFI with 1 or 2 shield distro doffs, subspace modulator (device) also...she's pretty much indestructible.
HG shields and engines, borg deflector.
pick up the deuterium consumable from the daily along with engine and shield bats that rounds out device slots. she won't turn on a dime but just doing pve you don't have to, everything comes in a predictable fashion. just plan ahead and position yourself.
Well, I would post my build, but it's much more of a...'kill you now' kind of thing, and lacks of lot of survivability. It doesn't die, but it isn't going to last forever in a fight. At least that's how my tac one is.
I would like to mention though, a few things about the Bortasqu' in all it's forms:
Tactical has the only KDF ship with 5 tactical console slots (Jem'hader bug doesn't count), and the engineering is only one of two ships that has 5 engineering slots (the other being the fleet Negh'var).
Of the three, I'd say the science (Command version) is probably the best. Primarily because it has two science consoles, and the 4 engineering still. That means you can possibly put 2 Field Generators on if you want, and give up very little engineering.
I would like to mention though the Disruptor Autocannon is a very potent weapon if you use it right.
