A low level pretended to be tank to get into a dungeon (after he got into the dungeon, he removed the role). This is nonsense so I left the group. I had the customary penalty time and once it expired (a little extra time passed before I actually checked), I had this message:

That is absurd and excessive punishment.
Another queue issue: complete a dungeon, "activity complete." Good. Now queue again, it'll find people, form group and...nope, no one gets teled to dungeon. You have to do it manually.
Another queue issue: after getting in (while standing in an overland area), it decided we weren't in the correct instance, kicked us from the dungeon and then did not move us into a new one.
