Ever since this feature was added to the tool, it's only caused problems for my groups when we're trying to do dungeons. A few examples of these problems include:
-Joining a random group, having at least one person immediately leave said group, and be forced to search for a replacement, while being stuck inside the dungeon, as it will teleport you back if you try to leave to farm or do something productive while you wait. You could also just abandon the group too, be able to leave the dungeon, but cannot queue up for another 15 minutes.
-Using the tool to scale a dungeon for the one or more players in the group who are not yet champion 160, having accidentally selected the normal instead of the veteran when doing the pledge, and then being forced to either complete the normal dungeon, or wait 15 minutes to scale the correct dungeon.
The second example bothered me the most. I thought the cooldown was to stop too many incomplete groups re-entering queue to search for more players. But when we have a fully formed group, we're not going to enter any queue at all, so why should we have a cooldown? If there is some other reason for this that I don't know, please explain it to me.
If at the very least, please remove the cooldown from fully formed groups, as it's just annoying.
