Jon was alone in the middle of the field charging the Bolton army. There was no one around him at that point, they were aiming for him. His horse even took multiple hits but he was somehow unscathed.
It is plot armour when they should have died, there's no way they could have survived the initial rush considering they were commanding the line from the front. There are also much better ways of showing hopelessness than creating a situation that feels completely contrived in comparison to almost the entire series to this point.
Plot armour isn't necessarily about a character living or dying, it's about how they end up living. I'd have no problem with any of these characters surviving if it made sense. They newer episodes are a victim of their past. Had the series felt more like a Marvel film from the outset I doubt many people would be complaining, but this is a series built on people's mistakes leading to their death and turning the odds in your favour, not defying them.
