Star Wars: The Old Republic destination servers confusion

Hello, I’m trying to set up SWTOR item on mudfish but I’m puzzled by the destination servers: mudfish lists US East and US West for servers, but in-game both US servers are for North America
Which server do I pick?

For SWTOR please don’t trust the destination because it’s too old item to use. :frowning: It seems I need to update the game item when I get a chance.

I think it’d better to follow Unsupported Games document to apply it…
