Scout Roll: Can roll for others?

[Synthlol]

I have all the scout items I want, but I'd love to roll for my guildmates to score them those sweet benevolence items. They've all told me that you're only allowed to roll for yourself, though. Was Aikons being sketchy, or is this actually allowed?

I get the feeling we're in the territory where it isn't against the rules, but is generally frowned upon. Except there are clearly some players that don't care.
