Sent out to those I have not recieved from. As a token to past fail. Think one elite challenges me with correct time after my fail. Thanks sir/lady!
Yes, now that we're in a bit of a rush, it's ok to send challenges even though you're not responsible for doing so (in a given match).
But it's of course voluntary, because you will lose token that you're not required to use. But sometimes it can be very good thing to send challenge to speed up organizing process, if you have tokens so spare. Now that we don't have any new managers on Season 5, it won't cause so big confusion (to receive challenge from someone they're not supposed to receive a challenge from).
Sir it would be - I don't think we have any ladies participating to HGL, do we? :)
