Yeah, she's got some insane strength feats even as "normal" Xena maybe as good as Steve's. But she's got comparable speed and the crazy pressure points.
For two, that chakram is crazy even compared to Cap's shield, especially if it's the magic chakram but the original is bad enough. Giving her a sword too just clinches it.
Both are crazy accurate but even Cap, with prep and foreknowledge, isn't going to throw his shield half a mile and hit specific targets that have to be hit at certain precise instants while they are all moving and struck from, again, half a mile away without seeing them.
