I am all for TMP and the damage it does to a realm of hippies. What I don't understand however is why a realm that is actively involved in a war should be fighting strategically useless battles just to avoid getting TMP penalties.
In Thalmarkin on BT we keep getting TMP messages during peace negotiations with Fronen. We have already taken everything we wanted/could and our duty in this war is now more or less to guard the eastern bridge. Last time it happened, we launched an attack on Jyl and had some fun looting, this time the negotiations have evolved, and while we're perfectly capable of finding some other battle, diplomatically it's not advisable in my opinion. Yet, unless we want our armies reduced to utter !@#$e we need to launch a new assault.
TMP is necessary to punish those few tree-huggers amongst us but please don't punish upstanding, warmongering realms who are not fighting battles due to a sensible, working strategy.
