1st point: Imaging spending a lot of money to weapon bonus on secondary weapon just to realize that weapon bonus on secondary weapon is not working, like why because billposter, psykeeper, knight (SNS) fully benefit the weapon bonus of shield and the effect.
2nd point: Blade Bloody Sword or Bloody Axe life steal does not work on secondary weapon like we spend money for that Bloody Weapons just to release you can only get the ICD and CC and the life steal is totally not working, that is the only advantage of blade having 2 weapon but we cant maximize the actual effect of the weapon
