In primals the hansels/ps1 make more gold off steal kos and steals when the enemy has sdp. If you had full sdp in a primal war and the enemy steal KOed you then they would get an extra 50-300m for the Ko
Its never been proved right but it hasnt been proved wrong still. Forgive me if Im wrong, I just keep it all on during Primal so I dont pay attention to the topic of figuring it out
It'd be stupid for anyone with decent spy defense to sell sdp... sdp fends off steals assassinations and scouts,leading to better control of the war. With no sdp, your clannies will be getting steal koed all day.
Rojo is right im afraid I taught myself through trial and error. However there are a lot of cirumstancial advice I can give. Also to adress the sdp comments here its same concept as adp, a really smart wc will use any thing to improve their chances and pots are one such tool. The best wars in my opinion are the ones you really have to think outside the box to win.
