Time and time again it happens (although not always!) and I still find it amazing.
While in a fast light I roll with a few team mates until we come head to head with enemy mech(s) or there-abouts. And if the positioning is good I then target the closest one and move in close blasting away to get some attention and then swing round behind them - they turn round to shoot me and team mates open up hell fire on their exposed rear then queue the violent explosion - simple stuff, but it works.
Although I'm clearly not the main threat, because I'm closer and they might well be trying to take me out with big Auto cannons or some mad Energy Alpha strike - they just cant resist it and then even on occasion start moaning about hit boxes etc
I didn't kill you, YOU did it to yourself and you just got Bonnie Tyler'd baby!
p.s. I don't really sing it . . . honest. . .
