If one needs to leave for real then this dose no harm to them i mean 30min for someone who has something to do i'm guessing you mean by leave you mean {stuff to do in real life?}then 30min is nothing. I mean think about a dps that has sat there for 30 or 20min just to have someone quit? well that's not fair so the lockout is a good thing that and for ppl that will rq at random or ppl who get what they want and quit a lock out is fair.
