I've tried the Unexpected Fire, the 5 times i've tried it, 3 times i've ran into it, once i've light 3 of my teammates on fire and the person who was chasing me and the last one actually worked but I then went to go back then mis clicked and placed fire right on front of me and jumped into it, I then lagged and couldn't move and was stuck in the fire, it didn't end well...
