Isn't it a balance to make everyone stronger?
Why designers nerf useful and interesting specialty rather than buff bad specialty to the same intensity as good expertise? nerf useful specialty doesn't make bad specialty more interesting, it just makes interesting specialty as boring as bad specialty. As a result, players choose specialty that have not been nerf , reduced operability, and more and more boring games.Is it not good for all players to feel that their favorite specialty is powerful?
From a psychological point of view, buff is more comfortable than nerf , nerf is equivalent to taking existing things from players,buff is equivalent to giving, and nobody likes taking their own things away.
buff does not mean simple digital expansion.Adding more functionality to increase operability is also an buff.
If we take the real world view as an example, progress comes from competition for excellence rather than who is worse. Only this kind of healthy competition can make products more and more useful.
