I guess at this point we'll simply have to ask what Tereso09 meant exactly - whether he understood the mechanics behind the leaderboard when he initially asked his question.Ain wrote: Exactly?
After the next saturday the fact that you got a tier 10 emblem the last saturday will not matter. That's exactly what I'm saying. That's a cycle.
However, if he did indeed understand the mechanics (as you believe he does) - and he may very well have - then it would indeed be useful to know when exactly a rank was obtained so you know how long it'll take before you get removed from the leaderboard.
For highest killstreak, highest target streak and highest bounty hunter emblem, I could make that work because those always have one fixed date of when you obtained it. However, for most kills and most BH target kills, that wouldn't work since all your kills from the past week are counted, so there's no single fixed date at which it gets 'reset'.
I believe we can put this particular discussion to rest - I guess people simply misunderstood what Ain meant exactly (and possibly what Tereso09 meant, depending on his knowledge of the mechanics behind it).
