lets get teh facts straigt.

Duck probably refer to the fact, that swords beat spears. Thats correct.

Now directly to the real problem. Armor and universal units. Swords have low armor, the katana got 5 (i hope im not wrong) and the ND just 2.
If you look at naginata with 9 armor, its a huge difference, especially if you look at the 22k games and what will be used.

While in 10 or 14k games mostly a few samurai units will be used, lets say 3-6, in a 22k game you hardly will see other units than samurai.
The problem is, that almost every single samurai unit fight till death and dont rout, you really have to finish the units off.

The signs are clear. Missles have a harder time to kill an armor-9 unit than an armor-2 or 5 unit.
Followed by other problems such as:

- bubblegum units, which will make your charge get stucked somewhere. If you bring a ND you want a clean charge! Thats possible in the first clash, after that you will have a hard time, while everything is mixed up like hell.
- armor, If you didnt ripped most missles, you have a very hard time to get your ND unit in, with 2 armor missles eat this unit.

While good player might be able to get some sword units clean in a spear, most people wont be able to do this.
So the trend is there and clear, 22k the balance is out of hands. I dont want to take care for the cavs, especially as the charge is bugged, the outcome too random. I go full spear-melee and get me some missles who are on steroids. If swods beat spears doesnt matter a second.

Bad player who lose the shotout, want to have a chance to win the rush after, so they go for highest armor in game!
