First of all, I completely understand why, when queue times are long, to pull players cross-regions and expanding searches to find faster times for these activities.
It's a fine system, even if I don't need it as an NA player. However, it's really frustrating when after finishing the raid (already eh because of lag, but w/e) when you stay in a server that isn't the best ping for you. In order to get back to queue for a raid in your preferential server, you have manually swap back to it and then get back into party finder.
This really messes up the grind of raiding over and over. Is there any way you could be sent back to your preferential region after finishing a raid that pulls you to another, or have some option in party finder that allows you to select a region to search in? Just something that would alleviate the unfortunate side effects of this system put in place to reduce the times.
