Engineering Team isn't as effective on the Command slot as Aux 3 is. Aux 3 runs on Aux power the more Aux you have the more healing you can do. This can do massive healing and a life saver in a pvp match ;) Engineering team doesn't work on that principle as much (As far as I am aware, it may have changed).
As for the Galor I've never worked with it and aren't intending to try to myself, but based on your skills u have at the moment I can work out what would suit you best.
First and foremost: What's the mish? Do you want to be a healer or a damager? Or a bit of both like myself ;)
If you want to heal or damage the consoles are a bit of a different mix, but either way engs can do both very well if worked out right.
Here is my suggestion:
Weapons: Single Phasers only with possibly one torp in the back if you are wanting to do more crits to hull, but if your a healer this isn't really that important. Standard phasers have a better firing arc and can be classed a serious damager. In essence a beam boat ;) If you go side on you can fire all phasers and compensate for the drain with EPS Transfer, nadion inversion, batteries and emergency power to weapons/aux.
As for BOs:
-Universal Lt. boff: "This is a tricky one": Sci Team 1, Hazard Emitters 2, Transfer Shield Strength 3 or 2
-Lt. cmd. tac: tac. team, Beam Fire at will, Beta or Delta (depending on what you want to do)
-Cmd. eng.: Emergency to Weapons or engineering team, RSP, Emergency to Shields, Aux to Structural
-lt. eng.: Emergency to Aux, Extend Shields 2 or Engineering team
-ensign Sci: Once again Tricky and dependent on what you want to do. Tractor would be good to grab them and fire the beams or use tachyon beam to drain their shields. (i'd have to see on the game)
(The game is down atm. Will have to double check)
Really it all boils down to what you want to do and how you want to do it.
If you need any help i'm in game, pm me on the site or access the Combat Officer Forum :)
