New/Halloween Map+Gamemode Idea

So I was just sitting around doing some thinking today, and as Halloween is quite close, was wondering what might be in store for us this year in terms of special events and whatnot. As I was thinking I gradually came up with an idea that I think would be really cool. While it might not be possible to do for this year, I still think it could be a contender for the future.

Name: Count Vladimir's House of Horrors!

Concept: A team of players is trapped in Count Vladimir's ancient and very haunted mansion. The must attempt to escape while staving of the various monsters stalking the corridors of the house. I suppose you could have two teams competing against each other to escape, but that might be pretty complicated.

Map: No pics :( The design style would be the inside of a creepy Gothic mansion, with lots of separate 'rooms' that the players can move between. Players all start in the same room, and have to collect, say, 5 keys before the can unlock the exit and escape the evil count. Keys spawn in random rooms at set intervals, so the players must explore to find them all. There could be lots of fun effects added to the map, including things like trap doors/secret passages that can move you quickly around the house, different traps that can activate against players, or can be used to slow down the NPC characters, and room- unique events, like a mad scientist raising FrankenMundo to life, or a bunch of ghouls spawning from gravestones. Finally, there could be variety of NPC champions as 'monsters' that hunt the players throughout the mansion. Think playing on horror classics with champs like Warwick, Amumu, Kalista, Sion, Vladimir, etc. They could be more powerful than normal (though not Doombots level powerful), but there could be more focus on evading and trapping them instead of always needing to flat-out fight them. I feel like this kind of concept could be really fun, very different from lot of stuff league has done in the past, and would actually lend itself very much toward strategic macro-play around exploring and evading/ambushing enemies enemies. Heck, I think it'd even be cool if was around more often than just Halloween, as it would add a great PvE experience to League.

If this idea sounds interesting, you want to add to it, or want me to develop the idea a bit more, Make sure to let me know, and I'll try to keep up with any questions or suggestions. Thanks for reading, and I appreciate your feedback!
