Tanks and healers who withdraw more than once, hoping to get an in progress run, should be hit with the 30 minute DF lock out.

Period.

I spent over 90 minutes in the queue for CT on sunday. I got my first party after 40 minutes (which i'm used to by now) but it took another 50 minutes to actually get 24 people to accept. That's enough to make a person quit playing, at least for a few days. If my FC isn't available to run with me and I don't see anything in the PF, i'm not gonna do instances anymore.
