Wait .. wait .. wait.
Here is how it works: The Unreal Engine uses a UDP protocol. UDP is a connectionless protocol. The UE fires off a packet into etherspace and forgets about it. If the client doesn't receive it, they'll have to wait for the next one (the UE wouldn't even know if the client received it.. it doesn't care).
UE compensates for this by the Client application predicting (based on motion and your current actions) where your character will be in the world, and moves you to that location. This may not be correct as the Server takes president over this, and that's why on really laggy servers you'll be jumping all over the map (as the Server tells the client "No, you're actually here").
Anyways, what I'm saying is that one person with a 200 ping will really only affect that one person. It won't affect your gameplay / ping, though they may seem jumpy. In other words, STOP KICKING PEOPLE FOR HIGH PING.
Cheers,
