to get into a 5 man quickly

use the clients chatroom feature (found bottom right corner next to friends), and type in "lfg" you will get into a room with up to 200 others. either make a lobby and invite a few of them, or wait to be invited. If a room is full, then type "lfg2, lfg3," ect. GL HF to all of us without 4 friends :')
