The dragon flag works on the theory of keeping EPtW and EPtS up 100% of the time. Simply running 2 EPtW will let you at least reduce the amount of engineering consoles needed to get the power to 125.. but you may even reach the cap without those consoles.. give it a try. If that happens.. you can put more armour.
This is the build I based mine on, ( though I made minor modifications to suit my need)
I'm kinda building a niche build (assimilated cruiser) with 6 beam arrays, the borg cutting beam and the borg torpedo, all packed in a neat bundle with the full borg space set. Promises to be tanky and deliver a nice punch. I so far have no trouble stealing agro from most escorts, so DPS is there.
The easy trick is to swap around your engineering so you have 2 EPTS 2 or 3 and 2 EPTW1. That makes you an absolute tank, gives you an extra 20ish weapon power always on, and still leave you 3 for heals or buffs.
More complicated, but something Im playing with now on an Odyssey and enjoying, is two Aux2Bat1 with 3 technicians, EPTW1, EPTS3, and then an Engineering Team 1 in the other Eng Ensign slot. Leaves you a LtCmdr and a Commander slot for big buffs, and with the Emergency powers and Aux2Bat always on, weapons/shields/engines always have a ton of available energy. Plus the cooldown on all your other stuff gets halved besides. Only real drawbacks are that is uses up 3 of your Active Space slots, you can't use Aux2Struc, and HE doesn't heal much because of the lack of aux power (still clears debuffs though).
Well the problem with modifying my bridge officer abilities, is that I tend to forget to activate certain abilities in the heat of battle, which is why I prefer to see if there's anything I can do passively to increase DPS.
