The tweet from Anamana summarizes everything that the game urgently needs to retain the players. As a complement to his tweet, the game lacks a working alliance system. What's the point of being in an alliance in NGS? There is no content for alliances, unless you have shown the alliance symbols, then you can see who is from which alliance. That’s it.
In summary, the game needs URGENTLY:
Alliance relevant content.
Dungeons and Raids. Non-tradable weapons to farm towards, like Clauzz weapons.
Boss rush (like Masquerade)
More repeatable quests.
Story cut scene collection to watch again. (Who remembers what the story was about after 6 months?)
