Sigh, here I am again. I think my next step will be finding someone who is fluent in japanese so I can complain in the Japanese Forum, maybe this way someone from SE will read this.
As stated in the Media Tour 2021 Interview with Yoshi-p:

So i'm here to present the information they clearly are well aware of but don't give a damn.
I live in Ponta Grossa - Paraná - Brazil(
Google Maps Link) and as you can see, it's quite far you know? The distance is 10.243 km, or 6365 miles if you only now the Imperial Units. Anyway, my internet providor is Oi (
Link), and I currently have a 25 Mb/s internet plan. I play using Wi-Fi, but from near server I get an okay ping and good internet speed.
As you see, this is my ping test for the Brazillian League of Legends Client server, which is located in São Paulo:

Omg, yes, if the server is close enough you can play with low ping, wow. 15 ms.
And now, this is the ping test for the Primal datacenter (I currently play in Lamia). The IP I used is 204.2.229.10

202 ms, yes, terrible.
Here's the thing: we have no way of knowing how many South American are there, but we are here. Our friends from Oceania got their own server after coming to the forum and asking for a very very long time, and I'm here to do the same. We know the rest of the world is not priority for you, we know you care first-hand for the japanese players, but we are here. We consume this game, we pay for our subscription.
I'm an endgame player, I do Savage Raids and all this stuff, and you know how frustrating is it to play with 200 ms? I use Mudfish to try to mitigate it, but it's not enough. I'm not asking for a brazillian server, a South American one would help us already. I don't care about translations and VA's, we only want to play with a decent ping.
