TL;DR: While I still support making the defeat condition the team losing all structures, a reasonable compromise that would accomplish Blizzard’s goals would be a 60-90 second timer for the player who lost all buildings to rebuild before a loss occurs. They must have a worker to rebuild, and the team lacking structures at any moment would still result in defeat. This would make the requirement both players have structures less capriciously punishing in rare situations where it would matter without any disadvantages.
I played coop since launch and had no idea this was even a defeat condition until it came up in a wheel of misfortune where we got propagators and I didn’t spread out buildings enough about 4 months back. I was counting on the fact my ally having buildings was good enough.
It’s incredibly stupid and unnecessary that BOTH players have to have structures to win. The defeat condition should simply be The team must have at least 1 structure , like it is in team games in ladder since release day 2010. I understand Blizzard wants some added incentives for cooperation but the disadvantages of having this mechanic vastly outweigh the advantages. Even in vs AI, the defeat condition is the team losing all structures. In team games, Blizzard had the wisdom to realize the defeat condition should be about the team, not the individual. Now that needs to be applied to Coop. Was this condition really in coop from the start?
This mechanic adds a totally unnecessary risk of defeat to brutations played with random partners. You could carry them the entire game, and then randomly lose at the end because they refused to follow instructions to build a few more buildings in obscure places. Painfully stupid. Utterly pointless. Bad design choice. This might be the most indefensible mechanic in all of coop mode.
There are already so many different defeat conditions in coop missions. So many different ways of losing mutations, especially with randoms. This is an extra middle finger to the player on top of all that and it’s extremely easy to fix.
