Just because your tactics didn't work doesn't mean tactics don't matter or that ships are unbalanced. There are issues with broken console powers but again, that isn't a ship issue. Hop in a BoP and see for your self. My Escort, even my Galaxy-R, can last significantly longer than 10 seconds against a BoP. Other better people can not only survive 2 or 3 BoPs but even kill some.
Don't give up on tactics just because yours didn't work. It takes practice. Maybe seek some help in this forum or even this thread.
