How would an optional, official parser be toxic?

[Bellsong]

To be honest I'd rather play a game where people are nice and patient with each other than one people just want to be nasty to each other. Given the language you used in you own post I think you just answered you won question on how parses would be toxic.

Yeah I wish everyone was nicer and more patient, then you wouldn't have to look at FFlogs to tell if someone was up to the content, you wouldn't have to parse to know you could rely on your teammates. People would be nice enough to only join parties at the level they can perform, and would have the patience to take the time to learn and get better for parties with a higher performance required.

And in case anyone did join a party they weren't prepared for, all would be well because they would nicely bow out, thanking everyone for their patience with the wipes thy caused.

Literally everything would be better.
