It would be nice to allow Shai to have access to blackstar for the Sol slot.
So when it comes to tagging of course you cant tag your awa weapon, which isnt a huge issue, I made a PEN Sol, but it does mean if you want to be "BIS" you should really get a garmoths heart too, which is just annoying. I know you can get the cheap hearts to make them stormy etc, but kinda feels bad.
Also for those who have put there money / time into Blackstar awa, for the PvE bros, would be nice to let shai get those buffs that come with the black star, like the monster dmg and reductions.
Last point, I also think that this probably puts people off tagging and giving a go at the Shai because of this and them not wanting to enhance up a Sol
EDIT : someone has already put this in a perfect way... https://www.naeu.playblackdesert.com/en-US/Forum/ForumTopic/Detail?_topicNo=25628&_page=2
