The other is just a general thing, probably the single most important aspect of off-system strip wars, has been left out of the guide. Spy defense towers.
Back in the Foxes/iG strip war of jan/feb/mar 2010, we all leaned this full well. Any account in either alliance that had no spy def towers was decimated. Even the mighty DeathMonkey was stripped right off the top of the lb, a feat few believed possible. It all came down to spy def towers.
When we would pick strip targets, the primary factors were that they had lots of money showing in allies on their profile, to make it really hurt, and that they had very few or ideally no spydef towers.
Targets with spydef towers are very unattractive. They have a permanent spy defense that cannot be negated. Yeah, your plunder suffers if you have spydef towers. But everything suffers if you get wiped out.
I managed to avoid being stripped by running a stupid high number of towers. I wanna say at my most paranoid I was running 12 towers out of the available 24 lands. Lol.
Realistically, that's ridiculous. We did some extensive testing at that time, and found the number of towers that was a safe minimum, I wanna say it was something like 4. 2 was better than 0, but 4 was enough to make stripping you very, very difficult. And the more paranoid of us stuck with 6 or 7 or 8.
If you want to survive a strip war, you will want spy def towers, no question. As to the number, I can't tell you. I would honestly probably look at some of the stronger, wiser players in iG for reference. They have such extensive experience in strip warring, I betcha that most of their power players have solid safe builds.
Food for thought.
If you're fairly diligent keeping your target pinned then you should pick up on it. Good comment, thanks
And yeah, the more you can strip at once the more effective the strip, good point.
