TigerBlooImmortal Many people, such as yourself may (I'm assuming) fail to understand how diverse swords actually are. There are few people who write about a MC with a rapier, gladius/spatha, executioner's sword, falchions, kopesh, hook sword's/shuang gou, sickle swords and other ancient African swords, and many others.
You see the dacian falx actually curves forward for armor piercing and is used much differently than a normal sword. In fact it was used to defeat the mighty roman army due to this.
It's not just a diversity in weapons needed, but a diversity in types of swords as well.
