Lore Based Map Selection for Post Bildgewater Event

First off, I think it's great that Riot is giving another shot to really expanding on the lore.

I've seen a lot of posts suggesting a 50/50 chance of getting either the Howling Abyss Murder Bridge or the Bildgewater Butcher's Bridge. However I think it would be more appropriate to base the location off the lore itself and offers a great opportunity to really draw attention to the lore in game as well as open up even more possibilities for lore based maps (I'm sure I'm not the only one who would love to see a Noxian Bridge).

For after the event, I would really like a system where the chance of getting the map is based on the characters present. For example if is in the fray, it would be more likely that the fight was in Bilgewater, whereas if is fighting, then there's a better chance it would be in the Freljord.

Therefore I propose that the system works like this:

1. Champions are assigned
2. The number of champions associated with a given geographic location are counted
3. The proportion of champions from a given location is found
4. The sum of the proportions is normalized to 1 (if the sum is zero, use 1.0/#ofMaps for each map)
5. The new proportions then represent the probability of any given map.

Here is an example of the system:

Red Team

Blue Team

Bildgewater: Demacia: Piltover: Void: Noxus: Shadow Isles: Shurima: Freljord:

Bildgewater: 1.0/10 = 0.1; Demacia: 0.2; Piltover: 0.1; Void: 0.1; Noxus: 0.1; Shadow Isles: 0.1; Shurima: 0.1; Freljord: 0.2

Since only Bildgewater and the Freljord have maps right now, we can ignore the rest of the locations.

Now we normalize: 0.1 + 0.2 = 0.3 1.0/0.3 = 3.3333 0.1 * 3.3333 = 0.33333 and 0.2 * 3.3333 = 0.66666 So a 66.66...% chance for the Howling Abyss and 33.33...% chance for Butcher's Bridge

Now we can select the map!

I recognize that picking the map after the champions might pose a problem, but I think this would be the best possible system. If you're playing the conman of Bildgewater you get to be more likely to con some travelers in your hometown then to travel to the ice cold Frejlord. Or if you're trying to unite a land, you get to fight for the country you seek.
