IIRC, it's less about us - the Warriors of Light - and more about the back-end of their systems where - because of our growing numbers demanding bosses have bigger and bigger numbers, it's getting to the point boss HP is getting worrisome and how it'll affect systems. So, the stat squish is actually going to hit the game as a whole, not only the Warriors of Light. Consequently, because we'll have lower numbers (and so will enemies) people are worried content will become more difficult despite assurances from development that it'll feel about the same in practice.
Though, one band-aid solution to crystal tower baiting would be to force equip the best gear when queueing for a duty or roulette. This isn't the best solution and is still manipulatable via just not having the better equipment on your person, which is why I said its a band-aid solution. I definitely hate baiting in roulettes as I'm generally hoping for more recent stuff when I queue it. Getting older content by chance is one thing, but being dragged there intentionally by others is an infinitely worse feeling.
