If you are capable of clicking on a desktop icon play a pirate use the rail pistol to snipe people at 5 miles range. or the shotgun to kill anyone below full health at close range.
Play ninja. run into people look at their knees as you scoot round em and spam any combo you want. odds are they wont be able to block but if they have a shield or amazing luck just start tap forward rather than holding it down . ninjas dont make a sound when they attack so it looks like the start of one. once you draw the parry start your combo for a free kill. oh never take your finger off sprint.
play a viking use your 5 ft wide shuri-caanon to take half their life away and get an easy kill each time if you jump or change speeds it masks the throwing animation making it impossible to see.
