New coop options

Hi there been playing StarCraft 2 since it’s release and I’m loving the coop but I do believe more could be added?
I know blizzard had a clear out of staff but what about letting the players or fans have a go ?
Would love to see a 3 or 4 player coop with more difficulties and the return of battle chest to give the old and new players a better experience

They said no more any forms of content except balance changes. The only way to create something new is to use custom maps :frowning:
