What types of ships do you intend the Polaris to be strong against? What should it be weakest against?

Generally speaking, the Polaris is an ideal ship for taking on small/medium sized cap ships, and tactically should be used to get in quick, deliver the torpedo payload and get out. The turrets will also be utilized to fend off any small fighters who attempt to make chase. The torpedoes can also inflict significant damage against larger capital ships and provide enough firepower to crack fortifications or powerful static defenses (think sieges or base attacks). The question as to exactly how much is a matter of game balance and something we'll be exploring together over time. It's a ship designed for and dedicated to combat; faster than larger capital ships and tougher than smaller ships, and as such, like any ship, it performs better or worse depending on whether you appreciate its characteristics and employ them accordingly.
