in fact i would give the defiant battle cloak or something because it is the worst end game ship in my opinion. i ran both defiant and mvam and the mvam was the easiest to work with. just because the defiant has a cloak everyones *****ing. deal with it. if people are skilled enough to smash you up and leave you crying then deal with it.
imo the defiant shouldn't have a cmd ltcmd and ensign tac boff i think if you switch the ltcmd for a lt. it would be more balanced. In fact i think you should switch it with the multi vector and give that a ltcmd to have them both balanced around each other. just a thought.
