Tldr - dev focus on beta and changing business model has been great, keep it up.
Honestly gamma needs a decent population to be effective. That's why the devs removed it in the first place. Gamma was introduced when devs thought they were balanced for a low population.
Majority of population thinks gamma is underpowered and only use it for fights/content. Production is definitely at an advantage but from what I Remer reading is that the difference between beta and gamma for a maxed out industrial was less than 10%. I don't think 10% production alone is worth the investment in a gamma base even if it is 99% secure from siege.
If gamma isn't going to have the population or balance to be effective content then I would like to see devs put more time into developing betas, ie missions Tele rework field terms etc. Those have definitely had direct and positive impact on content and activity. The new ep packages are perfect to attract new and old player to enjoy said content.
Keep it up devs, all I ask is keep the focus you have had because it's paying off based on everyone telling me how they bought new accounts and ep packages for all their current accounts lol
