Incidentally, Chaos vs Druzhina, I watched the battles and have a comment/suggestion for Chaos:
Split up more.
The usual thinking is "group up and fight together". This is not the CHAOS way and you suffer for trying it. Druzhina has more ranged and more polearms. CHAOS has much better individual skirmishers (especially when playing on NA). I watch a 10 vs 10 engagement end up with CHAOS being wiped but then I watch a solo CHAOS guy trying to sneak around the side kill 6 people before he finally gets shot to death with arrows.
Basically you guys aren't good at working together and Druzhina's strategy relies on them working together. Therefore a possible solution is, well....chaos. If you spread out, some of you will get massacred by Druzhina pikeman clumps but around the edges where other CHAOS members are able to fight people in 1's and 2's, you do well. And while conventional wisdom is that "streaming into the fight is bad", it might be what CHAOS needs to do -- not stream straight back into the central grinder, but basically everyone run in different directions -- enemy archers have no crowd to fire into (where they miss their target but hit someone else anyway) and Druzhina pikemen aren't good if they get spread thin. They want to fight clump to clump, not man to man.
Their best defense to this would be to stay in a clump, but then they can't protect their archers as well as if they ran out to meet you, and they can't protect their siege shields, weapon racks and weapon depot as well either.
In the battles I watched, CHOAS would group up and charge, then regroup and charge again and during the regroups, Druzhina was running out to grab weapons, drop them in a central location and someone's full time job was to stuff them back into the weapon rack. This person was completely unmolested as the clump vs clump battle raged a safe distance away. They kept that weapon rack running for 3/4ths of the fight, only losing it when CHAOS lost cohesion and started trying more flanking maneuvers by the 1's and 2's, which Druzhina had to counter by clumping up, forcing them to fight right on top of their archers and weapon rack.
In conclusion, CHAOS is using Druzhina tactics but they aren't as good at it because they lack polearms and ranged.
CHAOS should try fighting using "chaos" tactics. Your strength is individual dueling. Your weakness is group vs group. If you can't figure out how to quickly improve your weaknesses, then maybe you can find a way to play more to your strengths.
(Also, if you would supply your armies with a small number of heavy throwing axes, I would totally have killed those spawn camping horses...)
