For over a month (2?) there's been problems with the grouping tool. A few rare times it disbands the group entirely, leaving us to wait for the cooldown to disappear before we can re-queue. Or as in most cases (70-80%?) the entire group is removed from the instance instantly upon entry into the dungeon. The group still functions though, so we can, and most do, just re-travel to the dungeon by wayshrine. However not every player knows this and this too can result in the group being disbanded. But most of all it's just a really, really annoying issue. And I thought I'd voice my displeasure with this bug, as it's been around for far too long..!
