How about having an option to queue with other regions for dungeons and missions?
You can have it as a separate button from the normal auto-matching button, so any player can have the option to take the risk of playing with players from other ToS regions. Like you can have the normal auto-matching button labeled as “Auto-Match: Region” and the merged queue to be called “Auto-Match: Global”.
I’m suggesting this because there are times when the population is too low and you’d have to wait for 15-30 minutes just to get a full dungeon group. Having the option to play with other regions on different time zones would help solve that problem.
