Get in a game
host do the "pick a default setup and switch to Save setup to start very quick"
no time to repick and 15 players are somewhat forced whatever the 1 host wants to play.
I really rather have the option to vote for default setup during lobby. *cough* chaos *cough*
Default option upon entering lobby should be "host decided" though imho.
There's pros and cons to this idea and low priority regardless. But I feel like it'd be more beneficial than not.
Not a popular enough thing in SC2 arcades I feel like. Runling Run 8 is the only one I can even name off the top of my head, the rest have at best the option to have a setup be host decided upon lobby creation.
