I'm going to be using it with my Tac. 4 Tac consoles, Cmdr/Lt. Tac Boffs, +10 weapons, sturdier pets and the ability to mount dhcs turns it into a nice, offensive ship. Turn-rate might be a bit crappy, but there isn't much need to change facings in PvE anyways.
If I'd want to fly a Sci or Eng carrier, I'd go for the Atrox/Fleet Vo'Quv or Recluse. Better abilities, boff & console setup and bonus power for those professions on them, than on the Dreadnaught.
