I wish to change my build strat around to get it more in tune with the rest of the kingdom. I'm playing an undead tactician in a semi-ghetto. My current build works fairly well, I'm active, attack as much as possible and the kingdom has just won a war. During this war, we found it hard to chain high def provinces though and the opposing kingdom did have a lot of high def provinces. In fact all their active attackers had 8 or more defensive specialists per acre. We tried nightstriking some of that defense away and it worked fairly well, but I think we should be able to do it a lot better and faster than we did. I used about 2 TPA, mostly for defense, and about 10% watchtowers for most of the war and it stopped most of the ops done on me. For the next war I want to be able to NS our chain targets so I intent to up my TPA to about 3. Now the questions:
1. Is 3TPA enough to reliably get nightstrikes in on other attackers?
2. Do I still need the watchtowers and if so, how much should I use?
3. Should I be running thieves guilds to get those nightstrikes in and if so, how much should I use?
4. I've red on these forums one shouldn't use both watchtowers and thieves guilds at the same time, but it lacked further explanation. Why should I not use both?
