Well if you arenít going to PVP you can tank pretty well if you use a full engineer boff layout and forget about sci. It gives you some really nice staying power Ė you can run RSP1 EMPTS1 & engineering team 1 Ė chuck in Aux2batt1 with the technician doffs and you get a nice cool down reduction on all boff abilities.
If you are planning on PVP then you need to kit it out like any other escort and have a copy of sci team running, as you will get shut down by a lot of sci captains using their sensor/snb/combo.
You want to maximise on the 4 engineering console slots. Iím running teutronium, tetraburnium & diburnium armor and an RCS accelerator Ė this helps be stay alive a bit longer in a dog fight, but it all depends on how you want to use your own ship.
You only get one sci console Ė so you need to think whatís going to be good for that perhaps a generator would suffice. Personally I use it for my assimilated borg console.
