Hello, I want to explain my idea.
As I know Lordaeron is rates x1, and It's okay for me, but when we're leveling with a friend or just we make a group to make it easier the drops aren't sharable.
This make bored leveling with friends because you may take 20 minuts to complete a regular quest where you need to take "12 Items Quest" for each character, and it has low % of drop.

So this is my suggestion:
On Legion expansion blizzard has implemented a system where the Items quests are sharable for those players that are leveling in groups. It makes fun leveling together.
I know you will say "this is not Legion" but its only a suggestion. Complain how this system would improve leveling with friends or another players who enjoy leveling together.

Thanks and feel free to wirte comments.
