I just experienced a match of 4v4 where my team queued in to a group that only had 3 people. The healer never made it in. In PvE content, we can leave after somebody else does without suffering penalty. I attempted to see if the same would hold true in the Feast. Not only did I incur a 30 minute penalty for PvP content, but my rating also went down. I get not wanting to create a scenario where people can just disconnect to avoid losing their score, but the rest of the team shouldn't be penalized for someone else disconnecting. Before the season rankings start, there needs to be some sort of check in place that nullifies this impact to rankings.
