Some tank guilds could use a skill with which to hit more with a certain
damagetype and less with another. lessay you have a weapon that hits 50% phys,
50% magical damage. with this skill you could hit only phys or only magical
with the weapon, therefore making damagetypes a true bonus. IT is very common
that a monster resists atleast the other type you have available.
skills should be able to hit crits as well. the skills i am referring to are
offskills, like strikes, or bladed fury. i dont recall seeing crits on vb
either, though i think reavers can crit their skills with certain quests done.
