Do you enjoy hitting things with a needle? Somehow managing to block an axe blow with said needle? Being fast and cool? You should be a Fencer. Fencers are self-explanatory. They are quick, nimble fighters who use rapiers in battle. They don't wear a ton of armour, they can somehow use that thin sword as a shield, and they can and will bounce your 50 pound mace back at your face.
Fencers don't really turn up in armies because they need space to maneuver around opponents, which is a rare commodity in massive battles. Instead, they often get hired as mercenaries to protect cargo or mess up someone who stole some bread. In a way they bridge the gap between the Thief class tree and Warriors; their strength is quite low while their dexterity is through the roof for a fighter. Parrying is an art they've mastered and gives them the advantage in most 1v1 scenarios, but they obviously can't swipe fireballs to the side.
Honestly, they're not that cool outside of fights. They may be able to run errands faster than other Warrior classes but otherwise they don't get any special privileges in life. Fencers ARE good at deflecting falling objects though. Not actually catching them, but you can guarantee that they aren't going to get hit by the egg you're throwing.
