I'm fairly new to the series so if this is a noob question forgive me. I'm a bit confused with what the point of being proficient with 2 different weapons is?
For example, Ferdinand's default goals are Axe and Lance, and Caspars default goals are Axe and Brawling. Since theres no weapon triangle why should I master in 2 weapons? I was looking at steering Caspar towards War Master but they master in axes and brawling and I dont really get it
