A Possible way for Riot to make League of Legends Story more involved

Dear Riot and fellow summoners,

I was looking at Riot's shurima concept art, and i thought to myself " this place look so amazing, if only i can discover it more ". We all know LoL story elements is pretty much non-exsitence to most of the players, its a shame because just think of being a part of the Demacia vs Noxus war is pretty exciting or try to catch a super criminal in Piltover or even dive in to deeper story of Yasuo or maybe we can visit a Yordle's city,Freljord , the void or even Shurima ? Those places would make epic adventures.

How to do all this, like hearthstone, they have an option to play an adventure, defeating boss after boss like an dungeon and you get a great card at the end. So riot could make an co-op dungeon styles base on their stories, where as a team of 5 players (or less or more) play as keys characters of that event or chapter. For Example: as for the war between Demacia and Noxus, a mission could be garen, Xin Zhao, Lux, Jarvan IV and Galio try to infitrate a noxus castle through a battle that going on at the same time. Pretty much like Dungeons in WoW, where each of them has a story within. A 'boss version' of Darius could be in that mission so make it more challenging, and Draven and Sion ? and a reward can be as simple as ip or a skin.

Moreover, to make those scenarios have more replay value is after players finish it they can replay those missions with a different combination of teams and with several difficulties.

Just would be very nice to see more of the world of Riot has created and put my thoughts out there.

Derion.
