Anyone new to the PvP mode will most likely just run around and try to kill things before getting killed themselves like you described, and a lot of people especially try it out during these events.

I've had this problem in the Feast. I could only win 33% of the time despite never dying, because I only get 3 good people on my team 33% of the time. Once I got to the competitive rankings that was not sustainable so I gave up.
