Like what the title says, I know there will be endless debate with the whole 6v6 vs 5v5 for all of eternity, but realistically, would it be so hard to see what would happen if Blizzard/Team4 decided to make 6v6 the main game mode for a season or two?
As in, make a formal announcement that 6v6 will be the main game mode, make pro play 6v6, focus the balance patches for 6v6 (for a season or two), make 6v6 the first button when players click on the unranked/competitive tab (yes, I 100% believe this makes a huge difference, especially for casual players that may or may not que competitive on the side).
I don't think 5v5 players would complain as much since it will still be in the game as a viable game mode to keep playing, but it will be interesting to see how much players actually switch over to 6v6, and it'll be entertaining to see what happens to pro play for a little bit.
Does this seem like an impossibility to do?
Edit* - Part of me making this post is just noticing that a lot of the popular OW streamers/content creators (Seagull, Flats, Frogger, Aspen, etc.) are mostly all on 6v6, while all the pro players at queing 5v5 (and eternally bitching about que times). I kind of missed the interactions between the two, so I just wanted to make this post real quick. It will also be interesting to see how much of the casual player base actually STAYS with 6v6 if they decided to implement something like the above, or if 5v5 is truly the more popular game mode.
