Oly ranking

Oly npc doesn't show last period ranking eventhough many of us have played.

I think that it should show only when competition period will end.

But you don't know how you're doing compared to other from your class... it's a basic feature in l2's olys. It doesn't show scores, just your place among your class. Hmm I don't see the bad side of having it working.

Well it is working but listing is displayed only after every competition period.

By "after every competition period" do you mean after 19-01 hs? If that's the case, I tried at 04 to 06 gmt+2 and list was empty

Competition period is time period when players are fighting for points.
In short new listing is displayed every week.

Then, if i'm not missunderstanding, there's no way to know how good you're doing before new heroes come out, right?

Yes
