Nintendo doesn't need "saving". They're already well on their way to "recovery", and honestly, their losses were only in comparison to the massive gains they had made in height of the DS/Wii years. Nintendo as a company has never yet been "in trouble", and they still have billions of dollars in the bank, just sitting around. As someone pointed out before, they have enough money saved up, that they could post losses for the next decade, easily, and not "go under" from it. And quite frankly, it's Nintendo. They're not going to do that.
All this QoL shit is going to do, is give them more revenue in NON-gaming avenues, which is what they're aiming to do. It's not going to be gaming itself, Iwata has said that, and it's not going to affect their gaming business, which they will never stop.
P.S. FYI, just to anyone in general, suspiciously sounding as if you're cheering for a game company to fail, just because you prefer another one, is both pathetically sad, and a waste of anyone's time. Just like what you like, play what you play, and go on with your life.
