Varangian Guard ... overpowered?

Here at my level (25 reps) Varangian Guard is considered overpowered and overly safe. Yet I kind of like her because she's defensive, has an OK offense, and better yet her feint to neutral catches a lot of people off-guard (i like feint to neutral). But so many people claim she is "meta, overpowered, safe" and I don't think she's that good. I also like Black Prior, and funnily enough my brother, a rep 50, also says he is overpowered, yet other oeople say he is balanced. But I really like defensive and counter-attack characters so what am I supposed to do? I was wondering what higher rep (100+) people think of this. Is BP and VG truly unbalanced? If so, I don't even care. I'm still going to play them because I enjoy them.
