What bugged me about scenarios is that there was no connection point between the quest or zone in the game and the scenario outside of metaknowledge. Ok so there's a pandaren festival that gets attacked by stuff. Why do I care? Are characters I know involved as well? What's the context?

I'd like XIV to take the idea and improve it by tying it more to lore or give scenarios an unlock quest so that you get actual context and get you to care about them. Following my fictional Maat saga (during beta I suggested Maat be inserted as a young martial artist in training that is a recurring character through different zones), you come upon a hamlet that is on the brink of destruction by bandits or something. After the questline to restore the hamlet and help it stand on its own, you get access to a scenario battle called "Defend the Hamlet!" that you can queue up for. NPCs you helped during the quest line would appear during the scenario, and since Maat was wandering near the town during the questline, he even shows up to help every once in a while.
