wow the Zodiac quest actually has multiple quests in it. The previous ones were just.. one ot two quests then trying to get the weapon.

"Impulse Drive Weaponskill direction requirements have been abolished, allowing combo bonuses when attacking from any position."
"Heavy Thrust Weapon skill direction requirements for the additional effect have been abolished."

Them positional requirements.. finally gone. Finally free from the horrors of turning bosses! Still they should have just let Heavy Thrust be its own Fist of Fire or Viper/Wasp if they were going to do that with it. In my opinion anyway.
