I know not everyone is crazy about the idea of a weapon being able to damage buildings in the game, but more than many people are crazy about the idea. It used to be in the game and it was great if you ask me.
How about making it a server setting with a slider just like all of the other combat stuff? And while you’re at it, just make it so you can adjust how any damage is done to buildings in the server settings, making, say, bombs do more damage or less damage with a slider.
It’d be fun to fool around with. Then you can really set the pace of the server, either fast paced pvp, slow grindy pvp, or just pve. Kinda add that castle feel to your base if you want that.
