Because they're coming upward towards her from the ground, and its not just one tree she's on but quite a few in the general vicinity. Not all of them but more than just two, or three. If I really wanted to hurt your character enemy archer is still in the center of the forest on the high ground.

As for the blue boy he's barely holding his own, and Lancer is not going full out on him. If nothing else she does pity him because of hero's bridemaid. The only other option was to have Saber come up, and block them himself but he's not going to show up to later. Archer shooting them down is absurd given the circumstances and insulting. The guy in blue really isn't in it for himself just as Lancer says. If I really wanted her to Lancer would kill him. Originally berserker of red was to fight Lancer but since our berserker charged in face first, and left the others out there I needed to give him, and opponent and Archer doesn't make well just pegging people from the grey castle. Assassin is arguably the weakest of the enemy servants and isn't fit to fight either Lancer, or berserker outright and it would make little sense for him to engage her directly instead of staying in the forest. And Saber would run Lancer through in a one on one fight because of his skills.

Well, if you read what I wrote, Atlanta isn't staying in one place so unless these roots are faster than her, they are never gonna touch her while she's moving.

As for the boy stuff.

I don't care for his circumstances, neither does Atalanta. She's canonically the type of Servant that would shoot you in the back without any remorse if she thought that you are weak, simply because that's how nature works and her mind follows the logic of a wild beast.

If he got into the war grounds but can't hold his own, the only thing he deserves is to become prey, in her opinion.

If Archer sees another chance to shoot him again (even if it's on the back), she'll take it. But for the time being it's not her priority.
