In my experience, the fort will allow CR promotions to work, not nullify them.
Fort are far away. If ever the SoD comes earlier than any established fort or even math online, the defense on forest means their CR promos are useless.

People here sure are peacemongers

...my idea was simply opportunistic. Get the city if he doesn't whip (it happens sometimes) or making peace right away. Probably the city doesn't worth that much, especially knowing giving it back breaks all culture pressure we had onto him (thx
Dan). Anyways, war is hard to put into numbers and something looking inefficient can come efficient in long term. But looking nobody agrees, I give up the idea, but peace with Toku as fast as possible should be high priority if we still want Hammuragawa as future voters for us.
Yes, I think Tachy has the wrong end of this. I tried in my original post to point out that the fort is a two-edged sword, as it enables both city attack and defence promotions to work.
No, I wasn't even thinking of forts and I precised it. Defending on that forest which is the only path to attack DeerGold has better defense than the city itself even with second border pop. Unless we plan to build a wall for the meager 10 %, we have that forest with all defense already set up. And unless
DanF5771 has a special behaviour to share, I think
Sun Tzu Wu's idea to defend on that forest is a great idea. And CR are nullified in the sense they become useless for an attacker attacking a unit on a forest plot without fort.
Only healing process is the downside of that tactic, but I don't expect waves of stacks like immortal/deity; we're on emperor.
Yes, I look like I do not understand the situation quite often, I admit

, but when you mentioned those CR promos, then the idea came up of using that forest for even better reasons.
Unless someone has something very convincing, I do not retract yet defending on that forest. As you said, his SoD isn't ready, therefore we have time to prepare on that plot.
Okay, I am trying to recapitulate because it may something I forgot to take into account. We're not going for archers in short term and perhaps not in long term and it is the only units with special defense for cities and forts. Like its inherent 50% for city defense and CG promos.
Axes are our primary defenders and it can't get access to any city/fort promos. Then I don't understand why people wants to defend in the city more than the forest tile. Healing rate is one of few downside.
