Pros:
More people= more engagement and more dynamic matches
More people= Less relying on the individual self So it makes it the team game we enjoy
Beginner friendly = Since individual performance is less punished it lets people learn easier without being criticised
Less trolls = The smaller the teams the more impact Magpie spammers and newton rampers have on the game
Allows people to specialise = If its 8x8 if one person eco's the entire game it could be considered "trolling" in teams all welcome it should be actively encouraged
Cons:
Sometimes you miss a game = Can be easily fixed with a new matchmaking meta
Games too long = Do you really want your games to be decided in 8 minutes by a crow rush?
Summary:
Don let the voice of the few control the voice of the many, We play this game because we enjoy it, there are already multiple options for smaller games and guess what?!?!? people font want to play them. Lets all embrace what this game has as its unique selling point and play a large team based RTS!!!
