It’s same type of problem that happened on launch and in multiple other seasons, but not only, every now and then I get put into high ping servers in quick play and most of the time if I enter training. It’s the same thing as ever.
It make no sense why they would include high ping servers in their pool served to users from regions outside their own, it would be understanable as fallback if the entire region were offline, but doesnt seem to be the case.
Why go to the trouble of depending on the routing to assign, when you can just give the option for the player to choose the region or just by getting the latency from the user, it would be enough to assign him the region or multiple if in the US. Asking the ISP to fix routing issues or even changing servers providers to deal with this, seems like temporary and bad bandaid, to rely on ISP reliability.
