i queued up for over 30 minutes, still queued

i just realized that ranked ques take forever, i queued for over 30 minutes and everytime a champ select starts someone does something retarded in champ select and someone else leaves, this has happened over 7 times in 30 minutes, why does ques take forever now? it used to be like 2 minutes max, im still in queued as i type this rant
