This topic always goes the same way.

"Dps meters will create toxicity!"
"But toxic behavior is against ToS?"
"People will bully others!"
"But they can't, it's against ToS..."
"Statics will exclude everyone!"
"But everyone who raids uses fflogs anyway, lots of causal statics exist and it's been fine?"
"Toxicity!"
"But...?"
"Toxicity!!!!"

There's no argument here and logic has been presented a million times. The simple fact is underperforming players don't want their performance to be visible. Even if no one bullies them, they hate that others are doing better or being presented with proof they're holding a group back by not trying or caring. So they want to stick their fingers in their ears and pretend numbers don't exist. And that's the environment SE wants to foster, because in their eyes those players are potential customers and they can just push the better players to carry them.
