I would love for them to go beyond fantasy medieval rpg games and go more towards open fantasy medieval magic. Some creative new weapons to wield such as a scythe.
One form of weapon that I would love would be instruments, utilizing sound and instruments to cast spells or attack your foe. Harp, Bard, flute or maybe drums.
One last idea I would love to see is off hand abilities. Wielding no weapon or weapons at all has it’s own abilities for each class, it would also kinda make it the only weapon every single class can wield.
