Shared PvP places
I think this is unfair for the ones that are kicked out of the Top10 this way.
An example:

As you can see, I am higher in rank than Teedodo and FeWbAd, but they had the score 2034 before I did.
My suggestion would be that the person that comes in last doesn't come out on top, but on bottom.
Either that, or give the users shared #X positions, so that it won't hurt the Ranking Rewards.
