I understand the reasoning behind how this would be "toxic" on all scales of the spectrum here. But this game has too many DPS checks and pushing enough DPS to clear these checks requires skill and many players can improve themselves by having numbers to read showing them their progress rather than just blindly following some combo move that they read in a guide. I was following the common black mage combo but it still didn't help me knowing if I had too much downtime or I could have done better elsewhere such as timing of blizzard 3s yata yata. If you have an issue meeting DPS checks no matter how much you bitch at people they won't know it was even their fault without having the ability to measure things and I feel most people would improve upon seeing that they are not performing good enough to beat that content.

Another thing is that I feel toxic people are going to be toxic no matter what tools you give them. Still, DPSing in this game has too many variables in place that I don't think would allow someone to sit with top DPS at all times so these tools COULD be used to judge someone unfairly. I say allow people to read their own DPS in fights without anyone else being able to see it so at least when the leader is like, "DPS is too slow! We shouldn't be pushing 6 meteors" people can look over at their readings and silently acknowledge they are not performing well and know to shapen up.
