I am going to make a list from the glorious to the pathetic. My opinion of course.
Tie for black knights and crusaders.
1stBlack Knights: Having the best castles and fortifications, they are a mighty force on that alone. Besides that they seem to have the strongest calvary using oviod shields plated with armor. They also have well armed infantry, always fully equiped. They have a lack of siege equipment though. But they make that up with the best naval forces in my book.
1stCrusaders: They have the strongest miltary and the most noble and brave. They have a good fortications,a navy and have a sense of bringing the rebellious peasants and forestmen to justice! They have one the most deverse forces also. However they also have the most enemies in legoland. Thus not making no suprise if legions of forces surrond 6080 and 6081. But they have the most people so that won't be a problem. Plus the peasants support!
2ndForestmen: They have sturdy forts entrenched in trees and put in the middle of lakes. However they also have the advantage guerilla tactics and can intercept trade routes. They have no siege equipment or orginaized forces or tactics though.
3rdBlack Falcons: They have small fortresses instead of mighty castles... But they have a balanced force. Also they have naval defense and a small navy. But they have the abilty to combine small bastions to one mighty castle! But best of all they have the best catapult in my opinion, one of the reasons they are in 3rd place.
4thRoyal Knights: They have a strong castle, fortifications, and have a strong miltary. They use both tri and ovoid shields and use bows, crossbows, spears, swords, halebreds, and they were the first theme to use a chrome sword, thus giving them a strong miltary. They also have a small navy, siege equipment, and river tactics.
5thDarkforest: This theme has a focus on bowmen and swordsman, and even some calvary, lack of diversity. They however don't siege equipment, and lack of structure for helmlock stronghold. The other two sets were good.
6th:Dragon Knights: Not the best structure, and lack of shields, but they have the fantasy element. Also siege equipment has a odd design. The miltary consist of crossbowmen, variuos infantry and calvary.
7th 0r 8thKK1: a theme with a weak castle. But holds one of the most diverse force holding all kinds of troops, Strongest crossbowmen in legoland for the quivers and shields. Has adequate fortifications other than the castle which in my opinion is cool. Also has relatively good siege equipment. Also castle can be easily expanded.
7th or 8thVladvek forces: Called Vladvek forces for various forces under the rule of Vladvek. A strong strudy castle, and okay tower. But a very undevierse force mainly consisting of axemen and a small amount of crossbowmen.
9thWolfpack:Ranked low for lack of fortications and amount of forces. Also lack of siege equipment. However holds the element of suprise.
P.S wolfpack can be placed from 6th to 9th, but was hard to place please understand.
10thFright Knights: Weak design on all buildings. Weak to average artillery, but has the power of fantasy? At least they have a fairly well rounded basic force.
11thBulls: They have a strong siege force, and a good force, only lacking bows. However no builing for them to live in. Shields are a plenty though.
12thkk2: The worst theme and smallest threat, considering the castle design. Spinning tops for defense? Also most of thier calvary is replaced by rolling horses. They have but 10 troops in thier army. 4 kk2.1 heros, 2 kk2.3 heros, and four brave but foolish knights. The force has no horse calvary besides Rascus and the king. Also lack of ranged infantry will cause problems in the battle. Not to mention ten men facing legions of forces...
