I agree logs should definitely be opt in and not opt out. I've said that before. I've hidden all my data on there for a multitude of reasons.

1 being. Yes I parse but I don't parse often enough or religiously enough to upload it all to logs thus any parses of me on there are incredibly sporadic and random and not an accurate representation of my ability.

Second being like many players I'm tired of the endless treadmill grind replacing trash gear with trash gear with trash gear and as a result many of my jobs are behind on the I level. My mains only just scraped into alpha at i356 none of which is represented on logs so people would typically look at that and assume my ilevel is higher and thus my performance looks worse than it is. Especially with the speed at which power creep and stat growth happens more recently.

It's not a bad tool when used correctly but I do find to many people treat it as gospel fact when there's some rather huge margins for error in logs for things that aren't recorded. A badly positioned boss for 1 example can have a significant impact on your uptime and dps. Or badly placed aoes on the ground for another.
