How would an optional, official parser be toxic?

[HyoMinPark]

I'll consider FFlogs toxic until it becomes opt in rather than opt out. You've no evidence they are holding you back you've just looked at website they probably don't know exists or don't want to use.

Generally, though, when someone with green/grays joins a party, their performance well matches what you've seen on the site. I do sometimes check when people join PFs I'm in, and they usually do a pretty good job of living up to what their logs show. And this is for any percentile, not just the low ones. Having a few low parses but several average or above average ones is one thing; having nothing but low is another.

I consider people who try to sneak into farm parties or weekly 2-chest parties that have no idea what they're doing in the content pretty inconsiderate. Some people may be okay with carrying them, but not everyone. And not everyone should be expected to, either.

Thanks to you I learned about Resource Monitor. Now I can use it to check when the next time I start the game.

Not a problem. To open it, I generally do it through Task Manager > Performance tab. There should be an option to open it at the bottom beneath all the pretty graphs showing your performance/usage. TCP Connections will show you your latency to any applications that are using your network. Just look for FFXIV.exe; there are usually two entries for it. The first one will be your latency to the server.
