I've heard many people say that SC won't allow using upgrading heroes in war because this will reduce SC income. Yes, there have been many cases that when battle day is about to end and the stars are very close, players use gems to rush heroes to gain more stars.
However, I've also heard many people say that some suggestions won't be implemented because this will make the game pay-to-win.
What kinds of pay-to-win are allowed and what kinds are disallowed?
