This issue already exist at release. Dont expect any hotfix for this.
Currently the main issue for lag is something else, something that happens on most servers:
I do expect a hotfix for this issue. After solving this issue, most lag will be gone.
Please stop pushing this crap. Brasil server isnt bad. You distance to Brasil is far, so your ping is high. Therefore you have lag. If you have lower ping at Brasil server, like players in Brasil, then you will notice nothing at the server.
What is wrong is that the game picks Brasil, while it is clearly not optimal. So, what is bad? It is the algorithm to pick a server. Can you please state this correctly? Your current statement is clearly false.
So i hope that the devs will look into this algorithm and patch it, so it is able to pick the best server.
