This isn't true.
There is a broader and kinda interesting topic here about what should be a QOL fix, what should be a reward, what should be given away, what should have to be earned, etc.
Like players naturally want to see good rewards for content, but at the same time some of the best and most well designed rewards are the ones that fix real problems players are experiencing in the game. Sometimes those "rewards" get swept up and "given away" as ninja QOL fixes first, so there's less rewards available.
At the same time though, we obviously shouldn't avoid fixing problems just so we can give them away as rewards later. I find this a hard balance to maintain.
