I've said it before and I'll say it again: Neutrons are greedy bastards. They pretend they're so essential for buffering the repulsing effects of too many protons in an atom, but we all know that's just a lot of made-up BS. I mean, they're just protons who decided to hoard not just an electron, which you notice all the other protons don't mind sharing, but also a neutrino which they claim is maseless but we all know that's just them pretending "Oh this neutrino? This old thing? I mean, it barely weighs a thing! You wouldn't want one of these."
My point is this: Cross realm dungeon finder needs some tweaking because in the current implementation it is the favored tool of Neutrons who are directly responsible for nuclear explosions, which are highly sought after by terrorists. Yes, there is a link between cross-realm LFD and terrorism, you just read it.
Cross realm dungeons are a very good thing. If you've ever logged in at times when no one is on, such as as I'm writing this (2:30 CST), you might have noticed that things are quiet. Too quiet. That's the sound caused by 90% of the player population being at work, school, or unemployed and already too drunk to remember what a computer is. The remaining 10% are 90% bots and 10% sick people, 'sick' people, and unemployed who can no longer afford alcohol.
This makes it very hard to form a group based on only the population of a single realm. To make it worse, a low population or highly imbalanced realm can be like this all the time. So clearly forming groups across servers will help get things rolling. But there is a problem: these groups are formed primarily from sick people, lazy people, and unemployed people who desperately wish to be drunk.
Okay the real problem: It's on all the time. When it's 8PM and approximately the population of Greece is online at the same time, it is not hard to form groups from a single realm. At that time he cross-realm ability is unnecessary and serves only one function: to group up people who will never meet again and therefore have zero interest in each other or their reputation. Cue ninjas, assholes, ninja-justifiers, and more assholes.
At this point there tend to be two responses. The first is that I can still make groups the old fashioned way, at which point I call them stupid for saying something stupid and pointless. The second is someone asks why I want to delete cross realms and should we go back to needing to wait at summoning stones to form groups while typing over Chuck Norris jokes in Barrens chat? Same reaction as before.
I propose literally doubling the tank queue time. Yes, add an entire second. Use this second to delay group formation to see if players from the same realm will appear. As players come on, shuffle the order slightly to group up players of the same realm. On average queues would be unchanged, pushed up sometimes, pushed down sometimes, but never by very far. But on average groups would have more players from the same realm.
Technology cannot fix social problems, but it can cause them and if we are conscious of that, we can design technology to be less disruptive or disruptive in positive ways.
