Haha, is this a joke? The SC2 mapping community has been overwhelmingly negative about everything regarding the custom maps system. Five map upload limit, 10mb limit per map, 20mb limit overall, the publishing system sucks, tons of things are censored, using the editor requires online connection, no local hosting, no LAN play, no chat rooms, no naming games, player regions are blocked and seperated, completely unintuitive publishing interface... the list goes on.
"No current plans, but we're aware that there are concerns regarding the current limits for publishing and sharing player-made maps. The feedback we've received so far is good, and we're keeping a very close eye on how the system is being used. This in turn will help us determine how best to accommodate our players and the mapmaking community-at-large."
