If you are losing the game and your team is playing defensively, you need to stand carefully near key objects and use 1st and 3rd skills to make it very difficult for your opponents to get in. The most important thing is to prevent your opponents from reaching you or breaking your position, and then you can drag the game out into the late game by pushing creeps/soldiers from a long distance with your first maxed-out skill and constantly harassing your opponents.
