When trading you need to trade on Asia.

this is the way

It means potentially having to wait 1 hour for a trade if you're both in americas but separate servers and queues are high.

If the queue isn't 1 hour wait.

This must be blizzards way to counter jsp?

Queues are a global issue not specific to one server. Blizzard themselves said its due to a global character storage issue. So when the global character storage is getting gummed up all the servers are hit with queues. They said they're "WORKING" to move it to a more regional storage. We'll see how that plays out xD

Blizz testing out their new servers they bought from wish that didnt get delivered until now.

The way I see it is that they had the split server on Asia cause they thought it was gonna be huge. After actual launch they see now that NA is the most used. So they removed the split server from Asia and a week later put it on NA.

i just tried to spam, i can only land on .88

is the region based or no?

Unsure at this time, my friend who is in Texas was hitting .188's and .88's, I've only been hitting .188's personally and I'm in California.
