Are martial arts a matter of quantity or quality?
Let me explain : would you like to be more or less average with all of weapons (blunt, slashing, piercing, ranged);
An expert on just one type (If blunt then , staves, quarterstaves, maces, flails; or if it's piercing weapons , then stilettos, daggers, knives, short swords)
A master in a specific brand of weapons (bows and shortbows but not throwing knives or being a master in long and bastard swords but not katanas)
Or a Grand Master in one very specific weapon : Two handed swords, One handed axes, Scimitars, Polearms, Daggers, etc)
