-I know the Q&A covered this, but when you wait 10-20 mins on a spot waiting to go in a dungeon…is a big waste of time. That time you can do a map or two. The current matching seems to go by level range if 5 people are queued and they not within range get ready to wait a while.
-Daily Dungeon: add 2-3 per token daily dungeon dailies. Just similar to FFXIV where your added to the group waiting the most to lower the wait time. Sync the level, give bonus exp(10%+ per run) to those that do the daily worth their effort. This will help dead dungeon or people waiting 20 mins with only 2-3 people on queue.
_Merge NA servers. In Orsha, I used the population check addon. Not sure how accurate. Average 500-700 online, not counting people in dungeons.
