[The Dresden Files] Shouldn’t Dresden be extremely overpowered? (Spoilers for books 2 and 3 inside).

So I’m on book 5 of the series, and I keep wondering: why doesn’t Harry just go rage mode and faceroll his enemies more often? 

Despite being told that he sucks at evocation magic, Harry has some pretty insane feats. In book 2 he pacifies a human-form loup garou and his possibly spirit-wolf friend with improper spells (no verbal components). He then goes on to toss around said Loup-Garou in full beast form while badly injured and tired in a situation stacked against him. 

More profoundly, which is the real crux of my point, in book 3 he roasts nearly a whole clan of vampires while in a weakened state where he supposedly had no magic left and had his power mostly taken away by kravos. This is explained by Dresden having used his rage, fear, and desperation at being in a ridiculously unfair situation to fuel the spell. Then later he just ignores a hail of bullets Neo-style while wrecking Bianca’s whole family with an act of God. Yes, he had absorbed Kravos’ power, but that really should only have cancelled out the fact that he was magically depleted (and was Kravos that powerful to begin with?) which leads me to believe that his love for Susan is what powered him there.

I can’t help but wonder why he hasn’t used this power since that point or before it. There’s been plenty of situations that were extremely unfair and easily could have pissed him off. Since magic is fueled by emotion, he should logically just grow proportionally stronger to whatever situation he is in, since the more dangerous the situation, the more rage/fear/desperation he’d feel.

I mean, quite literally, kidnapping this guy’s girlfriend and trying to smash a sword resulted in a whole group of super badass vampires getting blitzed. Yet people casually send thugs at him and challenge him to duels as if he hadn’t achieved these feats before. Seems to me like it would be risky just to look at this dude wrong, lest he get pissed off and sunder your soul or something. 

In other words, his power level is set to just scale infinitely with how hard his challenges are, which paves the way for a comically OP character like One Punch Man, Hulk, etc. 

I don’t know, maybe they deal with this issue later in the series or there’s something I’m missing, but it just seems like he has incredible deus ex machina power that goes beyond what anyone else can do in this world. 

I.E. If wizards were that powerful, and many are stronger than even him, why is the Red Court even a blip on their radar? Get enough top tier wizards in one room (like in Book 4) and I wouldn’t be surprised if their subconscious desire to live reality bended the Red Court out of existence.

Harry has a lot of power, and it only increases as the series goes on. He's said to be in the top 30 or 40 wizards in the world purely based on power. However, he hasn't got much finesse or skill. He does explosions, not surgical strikes.

He mostly uses fire as well, for reasons which are clarified later in the series. Basically, after he summons the fire, it acts like normal fire, spreading, removing oxegen etc. So when he gave the vampires that friendly toast, he basically threw round a bunch of fire, and physics did the rest.

No spoilers, but as the series progresses Harry does get stronger, but so do the threats he faces. He's facing someone or something more powerful than him on a regular basis and has gotten good at winning against the odds with good preparation, allies and luck. And if course, occasional blowing stuff up.

As far as the red Court goes, they're no push overs. They have magic users of their own (like Bianca in book 3), and they also have the numbers advantage.
