If this happens, I don’t know about others, but I will surely quit. After the cost increase, I know Perblue doesn’t care about us F2P players. But 7th star? It’s not just they don’t care, it’s that they don’t even want us
And, what’s point of staying in the game where you are not needed? 
Give me a 7th star, I will automatically delete this game from my phone once and for all
Try to think of the others, not just yourself, but the whole playerbase.
Some players quit after the addition of the 6th star, and much more quit after the Gold Inflation. I’m just making predictions, but if the 7th Hero Star is added, along the 6th Disc Star if you will, majority, if not all, of the players will quit. Leaving you, whales, and loyal and persistent players alone in the game.
I’m trying to give a constructive criticism here, but the idea of adding new Stars will not just lower the playerbase, but will tarnish the name of PerBlue along with Disney or Pixar, showing that they are indeed, greedy, as the players call them (please don’t flag this, I’m not attacking PerBlue in any way)
My final conclusion here is – no.
Well I don’t know about other servers but server 12 is dying and fast and you want to introduce a 7th star no thank you.
6th star received a huge amount of complaints. I almost quit when the sixth star was added. I’m sure I will if the seventh comes, and a lot of people will quit, too.
I am also from server 12. Like most of the time, there are always some guilds recruiting members, even the top ones…so yeah, I can see our server is dying…
