This will never happen because it will indirectly hurt Oasis's profit margins.

On the top end, it makes the amount of "win" people can buy less, it's one less title to buy via purchase of certain ninja and more init.

On the bottom end, now there is one less reason to spend money in the game, you no longer need to spend on refines to stand a chance in arena.

So you are wrong in saying that there is no harm, there is a very real harm to oasis's bottom line.

Remember, to be a win-win situation, it must be good for both the players AND the company.
