Hello Devs,
sadly there isnt any change comming to the binding status of Blueprints for WvW Siege.
However the Item “Siege Masters Guide” aquired at MF Merchants which is required to create superior siege has also the binding status “soulbound”.
Could you consider to change this status to account bound. This way people are able of buying this item with skillpoints on alts they dont need anymore and transfer it to the character they want the superior siege on.
Best Wishes.
