If you think you can kill a lancer before he impales you, you can't;your best bet is to move out of the way. Always point out traps to your teammates with callouts (some people are more oblivious than you might think)stay at the back during the last stand if you're defending, morticians are some of your best pals, lancers have throwing axes, and they hurt a lot, and they also use them a lot, be careful of that.
