Maybe my process is too simple. If I am a DPS > DPS or Tank<->Heal. However all you have to say is "Hello" or "Hi" just something to start the dungeon or w.e off rather than being completely silent. If only 1 person says hello, they instantly get the Commendation as long as they are not completely helpless or rude for no reason and no "o/" does not count in my books.
