The game certainly needs a more active, and involved form of combat then is currently in it. Many efforts have been taken to make the PVE experience more interesting and more in parallel to the PVP experience. Now they need to start going the other way. A game I would look to is Titanfall, having creep waves, mixed in with the PVP can lead to interesting situations that require more thinking then the current game requires and would be a nice move away from the rock paper scissors mentality that is currently in the game. There is a serious argument to knowing that every character you are flying against is a human, but there is also an amazing feeling of stakes that having tears of enemies in a PvP experience.
