the game is already balanced in the since of pvp. what makes a game unbalanced is a difference in classes and professions(mmos for example) where abilities and skills are different with different functions and abilities. Some times those abilities can be more dangerous towards players with different sets of gear, or sometimes more dangerous towards other players unable to break CC based on their class abilities.
Starbase however is not based on those same functions of classes. My pistol and your pistol shoot the same, difference is skill. My explosives and your explosives are the same, difference is skill. Two exact copies of a prebought warship going at it with same exact plating and guns, the difference will be skill and teammates. Fighting teams of other players will depend on skill amongst your teammates(which includes working together, move as one, flowing system of teamwork) as well as properly being prepared(which falls in with experience and skill). This is also for players who are just more creative and smarter than other players and can build unique things. And that comes with knowledge and experience.
This game like many others is designed for community base play, you can be a nomad rogue drifting through space doing your own thing, but to get attacked and murdered by teams of players is not imbalanced its you getting caught off guard. A designed battleground instance that favors one team over the other in any way is imbalanced, coming across large forces than yourself or the company you keep is just unlucky.
So if your a new player and by the time you are ready to venture out of the safe zone you should already be aware of the possibilities of being hit. If your alone and you get taken out by another lone player, dude thats on you. If you get attacked by many players and get taken out while your alone that again if just the dice you rolled.
Make friends, join a community, this shit happens to new players and veterans alike in games like this.
