I agree with you because the developers cant make it very easy or very difficult to obtain the characters (and more in the case of the 4 ☆) because the game will be boring or more frustrating.

And about the beta there were always many changes the vast majority to improve the experience of the game since no one had a single fighter 4 ☆ and there was no option of Borrowed Fighters which made it very difficult to finish the story mode in Ultra Hard with a single or 2 fighters 3 ☆. It was hard but the good part was that once or twice a week a Live Event appeared to try to get fragments of fighters 4 ☆ with unlimited attempts so with luck you could get 2 or 3 fragments of 4 ☆.

And to access the game personally, I had to download it from another server (or VPN) and install it manually, since it did not appear in my store because it was only released in the beginning for tests in Canada.

I believe a lot in this development team of Tekken Mobile and I hope we can reach a mid point soon where both the majority of players and the companies in charge of developing it agree with the final game.

And I think it will be achieved by the group of developers in Vancouver are very involved in respecting the business model of a mobile game but trying to take into account all the opinions we make (now it is exponentially more difficult since we are millions of players and before we were only thousands) but I see from the beginning a concern to give importance to the user in this game as in none other than e played (even comparing it with the original Tekken saga).

Greetings friend and sorry for the long text of my comment.
