Playing devils advocate, playing my warlock when she was about 8 trying to do phogoth I got matched with a 7 and another 8. Now she goes in as a 34 doing the lvl 8 I get paired with other 34s and 33s. Raid matchmaking would get people out there easier, but it is 2015, get on your laptop or smart phone and get on lfg, I'll still use it if matchmaking comes because like you said, communication is key.
