I'm sorry, they just suck terribly. In fact, I'm just going to go out and say this flat out.
Any meta-game mechanic which results in one player starting the game at an advantage defeats the entire purpose of playing the game, and therefore directly renders it unplayable.
Why would anyone invest their time in playing the game when they can lose because the other guy had more credits than them because they just joined GW?
The entire meta-mechanics need to be reworked. My suggestion would be that each planet gives a total amount of mass income. This mass goes to one single faction-wide bank in the ratio of the factions that control that planet. Each player has a defined location on the galactic map, and moving from planet to planet costs mass from the faction bank. You can see which players are on planets next to the ones your faction has a majority on. This would also help counter one faction simply having more players than others- if you can't afford to move a player from his current location to where he needs to be, he's useless. It also limits the effectiveness of the much better players in the game because they can't fight on every front at once; and introduces some elements of tactics which currently don't really exist and adds some better incentives for in-faction co-ordination or even cross-faction alliances.
Gains in the meta-game should ONLY translate into advantages in the meta-game. Never in-game.
