This made me laugh. So, you want us to run EE quests once and done? More valuable vendor trash? I can assure you that without better loot, noone, and I repeat NOONE, will ever run EE again. You have no idea what you are talking about.
Players have a reason to run EE quests, favor, unlocks various patron rewards, higher drop rates, more valuable vendor trash
My elite farming runs were done in COMPLETE PUGS till ~2 months ago. My guild is me and my gf so no guildies. NOW, my farming runs are done with half friends and half PUGS. You have NO EXCUSE to not farm an elite run, there are so many ways you can do them, pugs or not.
How many of your elite farming runs are pugs and how many are filled with guildies and/or a few close friends that are not in your guild? Thats the difference, you have a body of others that are willing to spend the time to help you get some item, not everyone has that body of support
