I would do the Polaris and M2. The first for that hard hitting anti-cap destruction power and the 2nd for all around transport needs. Its also a money maker if you do trading.
Look, those blast points are too inaccurate for Sand People, only Imperial Stormtroopers are so precise.
I would advise everyone to go through their fleets over the next 2 days and get what they need before the sale ends on the 2nd.
That number is only for the current area you're in + global things they track.
Even on a loaded server, you fly out to a rest stop in the middle of nowhere you'll see an FPS increase.
