I explained it already earlier:
If you review our changelogs after Unity has been deployed, you will see a lot of bugs/issues and improvements made to the game. As we said in the Community Update, we are still aware of the remaining issues. For example, the biggest problem - performance. We are currently looking into solutions for newer server setups, which will enable us to troubleshoot and improve performance more easily. As you probably know some issues are related - so they cannot be fixed/solved without solving the "core" issue first, and in terms of performance, the newer server configurations will help a lot.Gamestore improvements have NO detraction from the game's development. They're handled by different people/teams altogether.
