I've been running some development playtests on the PBE recently. Something I noticed is that while a lot of the test games start out really solidly, they occasionally snowball into stompfests.
This isn't particularly helpful for testing new features, so I am adding the /equalize command to let players on the PBE "catch up" the struggling team's gold and XP to their current values. This means if you're having a good match, but lose a couple key teamfights, you can help us out by using /equalize.
/equalize is now enabled on the PBE right now and will grant gold and XP to the losing team.
p.s. I've noticed a few of you guys throw around the idea of allowing it in custom games on live. That's not a bad idea... but it needs a lot more work first.
