"Once again we would like to state that our game does not follow a Pay to Win model, nor does it intended to do so in the future.
You can get better looking ships with full synergy, yes, but regular ships are just as good. Some of them, when fully synergized are even better."
Just from a quick google
Premium ships are easier and much faster to obtain if you spend real money to obtain them (You can buy premium ships without real money however it is a much slower process), they also have non-combat benefits over non-premium ships. Premium ships are a great option for people that don't have the time to grind out credits for non-premium ships.
Non-Premium ships are bought with Credits
Premium ships are bought with Galactic Standards
Premium ships do not require repairs.
All Premium ships generate 20% Free Synergy. Non-Premium ships can have up to 5% Free Synergy.
All Premium ships start with full synergy.
Back during release you could not get the premium ships other then cash shops, this looks alot better now.
