The Voyager is a very heavy Heavy class ship, one of the heaviest and toughest of it's class. The main attraction of this ship is the highly powerful pulse, one of the strongest in t6 of MCST. A fellow heavy, the Rottweiler has a larger pulse, however this ship has greater defense and mass. This ship is quite similar to vanilla's Odyssey, with incredibly high shields and mass, very low mobility and a massive pulse. This ship is actually not particularly strong due to quite low energy, horrible agility and a very low fire rate of the main gun.
Overall, not a great choice, but not the worst either.
