As a nub I like to say I am actually enjoying the game!
I think any sandbox game dominated by a focused core of players will have issues, it's a lesson to developers that if you want active players early on to help you then they will obviously grow too powerful and organised (and entitled) to allow new players to think that they can get anywhere in the game. I said 'THINK' since I'm hoping that with the Gamma islands newer players will get a chance on the Betas to nurture competitive power blocks. One example is that Beta control points could be adjusted to make them more fluid and harder to own and so present a pinch-point for the flow of goods from Gamma to the markets in Alpha, this would mean that the established power blocks would have to overstretch themselves to dominate both. Spark Teleport is a bit of a killer when it comes to projecting power but you can't use it to transport goods and materials. Anyway that's one way.
The immediate concern NOW is to give new players more of purpose to play, at the moment their choices are either join the big boys or become future cannon fodder. With the markets dying a lot of the point of PVE is also lost and the missions do seem a bit pointless after a while, PVP seems hopeless as a new player unless it's against someone with comparable skills and experience, at present there is no way of cutting your teeth or learning and nobody wants to fight if there is no chance of winning, because that simply isn't fun.
The other immediate concern is to engage the older players and set them against one another, I'm hoping the Gamma islands will do that but I fear that it is more likely that they will just carve up the Gamma islands among themselves and keep sucking up the best resources, you should be getting them instead to burn up their stockpiles by fighting one another and so level the playing field for the smaller groups, I'm sure everyone can think of plenty of ways of doing this.
As I said, as a new player I'm enjoying the game, especially following the meta game and to be honest I've had my moneys worth already!
