Woah, no crit damage on PvP swords anymore? Wtf...
Anyway to answer your question probably keen.
wow its either double attack speed/pvp damage, or Crit damage.
if given the choice i'd go with keen this time (cos the new sets already give u nice power boost and higher multiplier the weapon will stack well), but if i drop the design for quick or intense is not like i'd be sad at all
