You also need to remember these aren't just normal warriors or even normal Eldar, thery're Harliquins. Some are taking it into account that the harliquins is aiming straight at the chest where some of the strongest armour is. Harliquins are super quick and sneaky they would go for the weakest armour or where there is no armour. Groups of harliquins are known to be able to take down greater daemons. Also the harliquins kiss is meant to take on necrons and has been for many years before the imperium. Now I do reailise that a primarch is tougher then anything else around but you taking about releasing a razor sharp 100m wire that cuttes and slashes flesh to pieces. I don't think it would kill a primarch but it would fatelly wound him and if it went through a primarch head it would certinally kill him imo.
