The beta stamp is kept there only as an excuse. Don't get fooled by it.
After all, the game already has a second set of Starter Packs available for sale not to mention that you are able to buy the gems.
Just because the game is bugged, doesn't mean it isn't finished. Every single, properly developed and managed game gets updated with patches, not only with content, but also fixes. And it's not only fixes which come with bugs due to releasing new content in new patches.
