i looked at wiki and saw that all monster families were strong/weak to shadow,elemental,piercing but nothing to normal
why not for future expansions make a family weak to normal and strong against all other types
so if your weapon is a DA,GF, 5* branish lines, flourish lines, alchemer lines; have the monster heavily reduce all damage it would take because of the elemental/piercing/shadow damage. i know it's annoying but there are way too many people using weapons with split damage and normal is the most common damage type so it needs to balance out
No.
The point of normal is that it's the base attack type, always doing full, regular damage to everything. Every other weapon type has a give-and-take. If Normal was ever strong against an enemy, it would have to be weak against other types of enemies too, and that would make it no different from the other attack types. Some people like having a weapon that's reliable in any situation.
