Please don't fix OP defenses by merely nuking them. Merely nuking defenses is just going to make the game exactly like it was before the wipe, but with a gluttony timer / reason to actually cook different foods. One step forward, two steps back.
Actually adding more mid-end game content is the better path forward. In their words, the whole reason Jorb and Loftar wanted to redo gluttony etc... is that they thought it would make future additions to the game more meaningful.
In no particular order here are ways to add content that would lower the OP of current defenses.Add hard to find + slot clothing artifacts that reduce damage from brazier fire or increase speed of wall/brazier destruction.
Add wells with with pure water higher than 10% pure to allow for somewhat faster biling in the 100+ range.
Add brick walls, Iron + Copper Walls, and then
Cannons for seiges. (Shameless plug for
my idea about only buying cannons in London.)
Other random thoughtsWhy do you torment us with corn recipes but no corn?
One benefit of a bigger map is to prevent horses from being OP - where are horses and other domesticated animals?
