Constant withdrawl from Duty Finder

It is very few and far between when I complain about something, but this has certainly been a big issue with me lately.

Why is it that in Duty Finder groups, most notably Castrum, that there will be 10+ times people "withdrawl" from the DF before the group ever forms? I'm not talking about AFK people not clicking the button, I mean almost immediately after the DF window comes up, someone withdrawls.

Anyone have any items why this happens? Do people click the wrong buttons, are people just trolling DF? Or is this something worse like people using some 3rd party programs that may be spam pressing buttons and canceling the DF?

Thoughts?

That was an interesting effect i saw with that dungeon, but i thought it was happening because i was mid craft when it popped, it gave me the withdraw notification in perfect time with my basic touch ability and it stopped happening as soon as i finished the craft.

I will need to test this in more detail.

I know there were times when the wait was so long for me, i'd start doing something else, and if i had changed class and was in combat, i knew i wouldn't finish in time to switch, so i withdrew. That's all i can think of.

With some of the weird troll groups I've seen I wouldn't put it pass some bored tanks queuing just to withdraw to get someone's hopes up. I've been in 4man groups that queue and rather than actually doing the dungeon pull trash by running around in circles and typing weird crap. Then there are the people that join groups and go afk. So there will always be the players that are just out to troll, but they're the minority.

But it's just as likely tons of dps queue and go afk while waiting and it's just a huge coincidence that they're all in the group you're being put in.
