I won't blame the admins as they are trying their best to serve the current players in IEra right now, nonetheless I think reasons of the decreasing of players are that they are very least new players trying out this game as they do not know this game existence.

So in my own opinion is to advertise IEra on Youtube so that many people will definitely wants to try it out how does the game works, I know many players have made some advertising video for the game, they are really good, but they just made once and no more.

Why don't just create a small organization where players and stuff gets to make some promoting video and post it at the advertising section? E.g.
-Create some website to simply introduce how Graal works
-Use Youtube advertisement to post these promoting video that are made by the players
-Continuously updating the social media (e.g Instagram, Facebook and etc)

These are just some examples that I think is necessary? Neither do I nor the players who wants to see the game dies off, because this game is one of our favourite, I hope you can use these ideas i suggested to use it wisely.
