- Fixed a bug (important on Battlegrounds if you are using then).

* A player can do more than 1 damage to a plant per hit, if he equip only one weapon on left hand and keep the right hand clean and receives Weapon Element buff, for example the post effect of Magnum Break. On battleground it means you can destroy quickly crystals and barricades.
- Also fixed the extra bonus of the leaf hand, it was using the bonus of the right hand.
