Every developer from every game has that same mindset. It's just a lot harder to get it right than to say it. No dev ever nerfs something with the explicit intention to make it worthless. It's usually just a result of a dev not wanting to nerf too little, so they nerf too much instead. And I really hope the devs of this game won't make the same mistake. It's easy to say they want to balance top performers without making them unusable, it's a lot harder to follow up on this without overdoing it.
So I really hope that the devs are very, very, very carefull with any kind of nerfs and
