One thing that most players miss in the game, is a decent group system, especially when playing in a larger party. I hope that in the future we will be able to create a group in the lobby or in-game, lock it and invite players to it. But the most important part is that you should be able to see the name of the player you'r aiming at if the player is in your group. That way you know that all players that are tagged with their name are in your group. I'm not sure this has been suggested yet. I've made a quick search in the forums and I didn't find any similar suggestions.
