The problem is the stack of same player in an lb with the same account or with a different one.
And the problem result very clear in hauntlet and shuyal planar arena leaderboard.
I never ever saw a competition were the same guy (or group of 3-4) won 1st-2nd-3rd-4th-5th and all the others placements prices.
Those guys have the best gears in the game and they deserves the top spots for sure, but what about a player that is satisfied with a 6th or 7th place and got systematically kicked out of lb because of the stacking recorded times of a top one.
Not to mention that some of those players do it intentionally to make banners "rare", and you know exactly what I'm talking about.
I don't know if the problem is solvable because it's really difficult to prove that different account are owned by the same guy without violate the privacy, but I want to expose the problem Anyway maybe in the future it can be fixed in some way.
