So, I know there are bugs with the dungeon finder that are unpleasant, but I'm referring to the types of people you are grouped with.
Now, this may get a lot of flak, but hear me out.
What if we created a "Ranked" dungeon finder specifically for veteran dungeons.
Essentially, as you do veteran dungeons, you are given a "ranking" similar to an ELO system where your ranking is based on your completion times and personal deaths (possibly other variables, couldn't think of any) in the dungeon. Your completion time can be compared to the speed run as a basis. As you do more dungeons, your ranking becomes more and more refined, with possibly an initial ranking determined based on your first 5 or so dungeons.
It would probably only apply if you are queuing up by yourself, so your ranking cannot be effected by your friends (with the possibility of having a "party" ranking but that would be more difficult). Also, I believe each of your characters would have a different ranking per role, to prevent a good dps from having a high "tanking" rank.
Essentially, a new dungeon mode would be added optionally (you can still queue for "unranked" for a faster queue), where it pairs you up with people of similar rank to you.
I believe this would help pair players up together of similar skill. Not to mention it would be something else to work towards of getting higher dungeon rankings (similar to trial scores).
Anyone who has played MOBA games such as Dota 2 or LoL would be familiar with these systems. This is still very unrefined, but I believe with help the idea could be better formulated.
Make PC NA raiding great again!
Down with drama!
