I've always thought it would be a good for a Lore type grouping system.
Like, if there was a "Guild" for every major city type on each Server and there was a new game type where you could only choose champions from that city. Each team got 1 ban and then they would fight it out with the champions from that nation.
Demacia
Weakness: N/A All Arounder/No Clear Specialty or Weakness
Noxus
Weakness: Scarcity of Junglers/Supports
Ionia
Weakness: Scarcity of ADCs
Shadow Isles
Weaness: Scarcity of Middle Lane
Bandle City
Weakness: No Meta Jungler
Bilgewater
Weakness: Champions are usually either all damage/little CC or all CC/little damage
Freljord
Weakness: Scarcity of ADCs
Piltover
Weakness: No Tanks
Zaun
Weakness: Lacks Direct Engage/Requires Enemy to Make Mistake Usually to Engage
Shurima
Weakness: Fighters are often VERY limited to a specific range always wanting to be close or far
The Void
Weakness: Small pool of champions, scarcity of Support
Mount Targon
Coming Soon Cause There Isnt Hardly Anyone from Here
Champions that are more individual-like could become, say, champions for hire that each 4 month rotation are sent to a "fitting" faction. This meaning that Aatrox would likely go to the Freljord or Noxus. Nocturne would likely go to Shadow Isles or Noxus. Maoki would likely go to Ionia or Demacia. Such of the sorts. There is probably a better way to put them, but this is off the top of my head.
There is probably more factions, but this is the big ones. Basically, you choose one of these factions, enter a specific game mode, then you get 1 ban from each faction. Then you choose the champions from your faction and then brawl it out. Whoever wins each match gives points to their respective faction. Every, say, 4 months, all players playing in the current faction get a reward. For each 4 month rotation that you have been in and won for your faction, you get a better reward than last monthly rotation. Say...
First 4 Month Win:
- Cool In-Game Border (becomes disabled upon switching faction, re-enabled upon switching back and winning a match. Can be toggled between your Ranked border and Faction border)
Second 4 Month Win:
- Cooler In-Game Border
- Mystery Skin
Third 4 Month Win:
- Even Better In-Game Border
- Mystery Skin
- 750 RP
Fourth 4 Month Win:
- Veteran In-Game Border
- Mystery Skin
- 975 RP
- The next in-game event/champion release is based around this faction
And so on and so forth. This would especially give players who care less about Ranked a way to have fun in the game and still feel like they are fighting for something. Plus, it's a lot more fun when you truly embrace who your champion is and what they are fighting for than just looking at a champion for their strengths and weaknesses.
Of course, there would have to be some requirement for joining a faction, such as:
- You must be Level 30
- You must have at least 3 champions who you have at least Mastery 4 with in that faction
This way you would have to have at least shown some commitment to the faction before joining. This also gives a greater meaning to the Mastery system.
Riot could focus on putting this in in Season 7 instead of adding in another complication to the game to throw things off again and continue to balance things around the current state of the game.
