Excellent thread! I only noticed two errors so far
1. where it describes max plunder and says you have to have lots of allies... You only actualy need one, if it costs enough. Ally plunder is based on the total cost of all your allies added together. A hundred cheaper allies or one more expensive ally produce the exact same plunder so long as their total cost is the same. If you look at some players, like BigTroubieInLittieChina, it's possible to get max ally plunder from a single ally, provided you volley it high enough. In some cases, that is the preferred method.
2. The overall lb description is not entirely accurate. It's based primarily on a combination of total current power (buildings plus allies) AND your number of victories. Victores are actually very significant, so should maybe be mentioned.
Other than that, didn't see any omissions or mis-statements. One thing I would do different is to not suggest that people quest away all their troops, ever, except for if they're not going to play more for at least 45 mins or an hour or whatever. That's a personal opinion thing, but the method I recommend is to regen troops to full, and whatever quest is the easiest one available labeled "very difficult", to do it only 3 times, and then regen and repeat. It's maybe an oversimplification, but keeping troops near full is the way to make the most money questing as it yields the highest success rate on quests that pay well.
