Offerings should prevent maps rather than force them.
Like the title suggests, addons should decrease the chance of a map appearing, with green addons preventing them completely.
The current system is flawed as a single player can force a lobby into a map which everyone else despises, this can easily kill the mood and promotes DCing during the offering screen.
