i posted something simillar about this earlier in day finding it hard understand why you develop a game with match making as a key component begin with but leave this out of the two most important strike/raid elements in end game content, ive been a heavy mmo player for last 10 years and know if this is case, then in game communication is more important than ever. either via a chat type system or voice either is really needed, a wave and dance just dont cut it in what is PS4's first venture into the mmo world on console.
