I mean beforehand he rekt two grunts and he still beat the Troll, even if in a rather inelegant fashion. He got knocked down by Saurfang, but anyone would get knocked down by Saurfang.
The point of the sequence was more that he's clearly better with the Light than with a sword, so he's not really a Paladin as they would use the sword first. Just like Thrall is better with the elements than with the Doomhammer even if he can use said hammer.
