Multi-Alliance Groups/Allied Alliances

I don't know if this suggestion's been posted but we should have alliances groups or something. I don't know the word for it.. It's like an alliance of alliances! I'm thinking like Warframe Alliances where you can form an "alliance" with other clans! Group chats can only hold 100 people so it's pretty hard when there's multiple alliances who play together. Also, smaller alliances can grow too!! Or just expand the alliance member limit haha but this would be cooooool and it would expand the roleplay possibilities!!!!

Well... there's always discord in the mean time.
