BLUEPRINTS BY CHALLENGES

Since the last update added new blueprints to craft, there some of these that are op to be able to any player just using the materials, also making structures useless like tesla cannon and holy hand grenade blueprint does to the evil church, who will go to evil church with a lot of money just to get a lance reskin? when you can just craft the best items of this structure in the lobby

i suggest adding an new challenges part to get blueprints by completing challenges, making the op items blueprints unlockable by completing the challenges, also can be used to make new blueprints

EXAMPLE CHALLENGE: (this can be chaged if devs wants)

-Tesla cannon: kill 75 enemies with tesla cannon or shoot it 20 times

-Gunpowder barrel: blow up 30 barrels or kill 50 enemies using the gunpowder barrel

-Holy hand grenade: Use 10 holy grenades or kill 100 enemies with it
