How would an optional, official parser be toxic?

[Deceptus]

You design a game around DPS checks in raids yet deny your community a tool that shows how they perform.


I could wipe 30 times on a boss not realizing myself that I do 25% less damage than some one with the same job and similar gear.
My group has no idea either why we are not meeting the DPS check either aside from 'we need more damage'.
The game itself doesn't provide me a basic tool to see how much damage I do in a raiding environment.

If people do not know that they aren't performing well they won't improve either.

This is basically what it boils down to. And using a tool and informing someone they're performing sub par is "toxic".
