ok.. I was just playing in a party in which we owned one of the other teams. So it was down to 1 team and our team. 1 minute left into the game, we said ok, kill the hero. We did. Guess what? We still couldn't capture altar. Why? Because some warrior and some monk was blocking the "spot" in which to capture altar. Our hero couldn't get to the spot.
Kind of gay if you think about it. They had like several players all cramped up in the middle and because of that, we lost the game even when our opponent's hero dead.
