Gotta respect it. Worst case scenario, Brandon dies and Torrhen can say that his half brother was going against orders and went off on his own. Best case scenario, you kill three dragon and beat Aegon. If you’re Brandon and manage to kill even one dragon, you’re still the legend who killed a freaking dragon.
To be fair to Brandon, Weirdwood Arrows were later proven to make anyone into Robin Hood. He probably could’ve done it, but Torrhen probably didn’t want to watch his brother potentially die.
the north could easily win against the dragons they have the exact same advantage dorne has which is a vast barren land with a harsh environment torren bent the knee because aegon told him about the prophecy of ice and fire
