I understand your points, but the problem is that there's simply no reason to go and live on Betas right now because Gammas outshine Beta's industrial capabilities by a long shot and Alphas outshine them because of the safety of the islands combined with only slightly weaker combat and industry.
Only part where Betas shine are Rank 5 spawns and those are probably not something a newbie would want to farm anyway, meaning Newbies are just flat out better off on Alpha. I didn't mention Beta missions here because after the recent nerf of removing chain explosions between waves, even Rank 4 spawns on Alpha generate better results when you take in the time/cost of tokens.
If no-one has any reasons to try anything on Betas and Gamma sieges are only PVP opportunities, the game becomes stagnant. I enjoy Gamma sieges but a lot of players have quit from my side only because the lack of PVP. I'm sure the number from other sides is even bigger lol.
But who should live on Betas then? Whenever a newbie sets itself up there, it attracts a lot of attention and they just get slaughtered by the vets who have advantage in EP, experience and equipment. If it stays like it is right now, Betas stay deserted wastelands and only PVP these newbies can do is Gamma sieges.
I agree that moving Epriton to Betas is not the most sophisticated solution but it's something that will help the game to stir up some conflict in the coming months. Betas now again have some meaning and could potentially support whole corporations not wanting to build on Gammas. The game is stagnant right now and something needs to change.
Lemon, you might say now that the change should be siege bots, but that doesn't fix the issue of Betas at all. Still useless and still only PVP for newbies would be on Gammas.
(I remind you Tuxes suggestion of removing Epriton from Gamma structures btw, maybe after this post some people can see the wisdom there.)
