DF Lockout needs to be adjusted/looked at/reviewed

[Volsung]

Prime example. Garuda bonus window is up.
Someone has a PF group up for Garuda.
Couple of us join but it's not a full party. Party leader closes PF and ques group up.
Party leader receives a tell, he invites the person into the group.

Party makeup has changed. Your registration is withdrawn.

Why am I locked out of DF for 30 minutes?
I thought it was 3 strikes withdrawing when the que had popped! That's 30 minutes of the bonus window GONE! Through no fault of my own! How was this a good idea?

This doesn't add up. I've added people to my party while in Que many times. I get that message
and am always able to put my DF back up.
