I found one interesting thread and would like to offer my opinion.

Currently team sniper matches(omit:tsm) are mainly on the German and French servers can playing throughout the day, with the Asian servers can matchmaking only during limited evening hours.
But the tsm rank board counts for all regions in common, making it easier for users who play primarily on the German and French servers to earn points.
The only way for users who normally play on Asian servers to achieve high rankings is to play on French/German servers with high pings of 250ms or more.
If guys want to adopt a system of kicking players over 150ms, the only way to do it is to have a separate ranking board for each region played and reward each one.
