Why don't we just remove TMP and see over two months what the difrence is.
I bet 20 euros there will be more wars instead of less.
There is no need of such feature.
If we really want this feature, we could use this feature for a new bankers option, war tax perhaps?
activating war tax could allow lords to raise taxes with 3/5 % and activate the modified TMP feature, if you dont fight battles, tmp will hit hard, but only if you enable war tax.
