LOL Dungeon Crawl?

this is a hopeful and doubtful idea considering even bots don't get much attention but...has riot ever considered making a diablo-type dungeon mission/expansion for league? Using the champs from the game in an expanding dungeon type scenario would be pretty cool..it'd also draw in more players and be an extra game mode for people not interested in the competitive scene. even just a one off with varying difficulty would be an interesting new way to try out new champs.

not really looking for much just had to get it off my chest..i know they wont do it :/
