If you cc a sam and los him, you just survived the sam lb because the debuff will be gone when he gets los back, which is far better then trying to turret and die anyway because the shield either didn't come up fast enough, or you die anyway because you're left with 6k hp which is nothing.

I KNOW IT DOESN'T DEBUFF THAT'S NOT THE POINT.

You AIN'T surviving a sam lb as machinist with that crap shield period unless you're fighting in FL maybe then ye your point is valid, now your team is down to 4 and prob loses ground because of it, how the hell is that a better situation then los the sam, then kill him and gain ground meanwhile, and when he returns, be more carefull and bait out the chiten instead of the actual debuff then kill him again.

In what world is facetanking that lb a better option than just cc and los then removing the sam from the field, you gonna facetank as a machinist every 120s?

And yes turret is good in general, but NOT vs sam lb when you got debuffed.
