Not sure how people would feel about achievements. Like I have an alt that's sitting right at the end of 2.0 msq. Only really made them so I could attend a wedding on the server they're on. Yet if this applied to everything they'd have achievement stamps for things they don't even have unlocked or are even at a high enough level to have done. Wouldn't this also allow for people to stalk and harass others? I mean yes they would need to look at the achievement date stamp, but I feel if they're already stalking a person they probably already have looked at that info. Yet now they'd also know about any alts the person made in hopes they could enjoy in secret.
