So I started this Aurum Vale, healer was new, we go into the first boss, healer gets overwhelmed, we wipe. He quits. We are stuck there with 3 people waiting for a healer, another one enters, he realizes its aurum vale and insta leaves, so we keep waiting for a third healer, and after like 5-6 minutes of waiting I leave (we were 3 players, 2 DPS and one tank).

I get 30 minute penalty? For real? Aren't you supposed to get penalyzed if you leave FIRST? What was I supposed to do, sit there for 30 minutes waiting for a healer or else I have a 30m penalty? Please check this SE because the system is either bugged or makes absolutely no sense.
