That's fine, it can be the point that she stomps him utterly, but then you don't show it from her perspective, you show it from his. You start by emotionally connecting the audience to Bolvar, which to be fair to blizzard, how do you do that to such a nothing character... to be less fair, he's their character. Once the audience is invested in Bolvar, doesn't have to even take longer than a few seconds, then you show him get utterly wrecked by Sylvanas while we watch and root for one of his giant floating rocks to hit her. This gives us some hooks into what's happening, is the emotional manipulation a good story works on us.
Instead we follow her while she walks all over a guy and easily tears the veil of reality. Oh... okay, great?
