Is this truly wrong?

[Granyala]

Im sorry but the first two points are just false, logs are very reliant on player ability

Of course player ability factors into it but given 2 players of equal skill, the one with a significantly lower item level won't stand a chance. It is simple mathematics.
Yes, the gap isn't as ridonculous in XIV as it is in WoW but gear is still of paramount importance.

If you parse yourself as a 350 alt you won't stand any chance against a 370+ that knows what he is doing. Pretending otherwise is ignoring the truth.

I simply said to the group, thats gotta be better. And they responded with something surprising.... "We cleared it, you didnt die or get grabbed, who cares"? Before I could reply.... another person in the discord said, "you did better than me and I have better gear, who cares"?... So then I asked "why are you logging"? and they just said they only cared about themselves, for personal benefit, and dont judge others so long as they are clearing

And thats when it dawned on me, no one really SHOULD care, unless you are way under par and/or dying (causing the group to not clear).

Pretty much my stance. I look at the logs 95% in order to assess MY performance.
I only looked at others in depth when we somehow struggled to see whether I could pinpoint any issues and try to help.

Logs are a wonderful diagnostic tool once you get past the %ile / DPS E-peen contest.
