Per Kabam Miike:
Every champion is worth points, but placing multiple of them will not get you multiple points.
Say you get 100 points for Each Champion, you placed 2 Magik, 2 Spiderman, and 1 Hyperion. You'll get points for 3 unique Champions.
Now, say you placed 1 Magik, 1 Spiderman (Stark Enhanced), 1 Spiderman (Symbiote), 1 Storm, and 1 Hyperion, you'll get points for 5 unique Champions.
But this doesn't only affect one player... It's across every player in every Battlegroup. That means that if your Alliance decides that every member will place an 1 Ultron, 1 Luke Cage, 1 Nightcrawler, 1 Guillotine, and 1 Civil Warrior, you only get Diversity points for 5 Champions. Because there aren't 150 unique Champions in the game, you won't be able to get diversity points for every Champion, but you can still get quite a bit by varying it up.
Hopefully this means that you won't be running into an entire path of Nightcrawlers, or 5 Magiks as often!
This means a Magik placed in BG2 will not get diversity points if there's already a Magik in BG1. However results from the first AW have shown this is NOT the case, rather each battlegroup is getting points individually for diversity regardless if a champion in BG1 is also in BG2.
Is this the correct behavior? If so
@Kabam Miike you should edit your post to clarify, if not, that's something your game team needs to fix. Because this will impact how alliances select their defenders.
