What do you really think would make this game gain more players again?

So there are a lot of different voices / posts about what the game needs, stuff like Operation Health is obviously named a lot of the times. Still, I was thinking a lot about what actually will make more people play (or come back?) to the game and that's why it would be interesting to have one discussion about this. So to clarify, it's not about what YOU as someone who probably currently plays the game would want to see but what they could do to actually make the player base grow again.

As much as an Operation Health is needed to keep players at the game who are currently there, I also think that an Operation Health wouldn't really matter for newer players and/or to get more people trying the game. And after all, it's about getting new people to play and keep playing our beloved game so the devs can afford to keep working on it.

So, what would you think would actually matter? Would be awesome to have a talk about it.

I have kept most of my opinion about this topic out of this post so people don't just downvote it cause they disagree. I will surely talk about it in some comments, if there are some lol.
