as I said on the main post, the community board is streamed while the user is looking at it, and stops when its closed, this means you have a real time view of all PvPs/Etc listed on the toplists.
for the sake of this example, PvPs increase by 100 each time.
The design is simple to make the above functionality viable with minimal latency
Now imagine a server with 100 people PvPing for the first ranks, isn't this toplist doing its job? Myself, I can't wait to see it on the live server
