How would an optional, official parser be toxic?

And this is why FFlogs is Toxic.

Because I have expectations when I clearly label my party "farm" or "O9S weekly clear"? How dare I want people to know how to play their parties in Savage!

FFlogs is basically a resume. Of course, you just walk into a job, sport or any group activity, claim you know everything and said group must accept this or they're horrible, toxic, people, yes? In fact, let's compare! If you were on a Hockey team and needed a fill in for an upcoming tournament, but said fill in couldn't couldn't pass the puck, repeatedly got deked out and essentially couldn't keep up with the skill level of the team. Would you be totes okay spending several hours being "nice and patient" with them? Would you be annoyed they signed up in the first place, knowing the team expectations being woefully ill-prepared for them?

Bear in mind, if you show them any video evidence on what they're doing wrong—even if it would be a clear help—you're a toxic, horrible, person.

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.

But it isn't toxic a Samurai doing sub 4k sneaked into a Savage weekly and clearly have no idea what they're doing, thereby wasting everyone else's time? How about a White Mage who can't properly heal? Must be my fault for not staying in Tank Stance the whole fight because how dare I expect to be healed consistently?
