FFXIV players are so obsessed with DPS

[BabyYoda]

I mean... I agree with you, but is it really the players who are obsessed, or the game itself is obsessed and forces players to only care about dps?

It is actually both,
Jobs designed around DPS as a 1 factor to make job viable,
Player also that I find ingame is so obsessed with it and it is the only factor that developers have for players to be better at
