This is a direct incentive for better gameplay.
An extra feature that, like classes, personally increases my interest in the game.
For example, chess. Why are electronic clocks being introduced? To avoid imbalances with flags, so that everyone can see exactly how much time they have left, instead of guessing. This is really needed. But why aren't they introducing new pieces? For example, why have two knights on the board? You could remove one and replace it with another, creating more options and making it more interesting. Because nobody needs that. The point of the game isn't that.
