To those who said it's hard to win fights - Smash Q over and over throughout the fight, this will cause them to miss incoming hits on you and doing this I have successfully 'worldstarred' teams of 3 or more.
To those who need practice with the bow - ready an arrow in your bow at all times, have your chaser follow you into a tight or narrow hallway like in the back of shops or alley ways, as he enters the passage aim your mouse over and right click instantly followed by a left(this will shoot skipping the aiming animation) if you missed Q his face and continue to kite him, rinse + repeat till dead.
Shotgun - Don't even aim, just click and watch teams die. (rambo'd 6 armed men last night with one)
