Well, cavalry is going to be more difficult to deal with for sure.
For comparison, in 1,8 using 100 legionaries vs. 100 T6 cavalry and ordering them to countercharge let to a consistent 60 to 1 K/D ratio in favor of the legionaries. Now, it appears to be roughly even.
Cavalry did better against a defending infantry formation and I dont doubt that cavalry would win in that scenario post 1,81.
My game install may not be updating appropriately between versions, but I can't tell any difference between 1.8 and 1.8.1 in regards to cavalry.
10 Khan's Guards against 10 Banner Knights will get 10 kills and take a whopping 1 casualty.
HOLY **** FIX THE GAME
Thing is it's simple enough to "fix" Khan Guards by removing the Glaive, giving them a spear or saber.
But then they are going to be pretty useless other than as a horse archer (though horse archers are already pretty strong, so is that really a problem?)
Simple truth is weapons aren't very balanced in this game. Weapons like the Glaive and Billhook are stupidly power "one hit" weapons, with the only downside being you need some swinging room. Also I think the damage zone of these weapons is too generous, pretty sure there's been times where I've hit enemies with the shaft and that still does full damage. There really needs to be a more concise sweet spot for full damage.
I can overlook a number things, but the fact SnailWorlds in 2+ years of Early Access hasn't done anything to really balance weapons (other than pike bracing) is pretty concerning. I can accept some "wants" as being better left to mods, but it really should not be the community's job to balance weapons. It boggles my mind how absolutely useless spears are on foot. They are good at stunning horses, and that's literally it. Spears/polearms were literally the most widely used weapons in antiquity (granted a lot of that is due to cheapness and ease of use), but this game would make you question hunter-gathers for using spears in place of clubs to kill.
Uga: "Look! I have created stick with pointy end to kill mountain lion!"
Boga: "Why not Uga just use club? Club kill mountain lion in one hit."
*Uga attempts to stab mountain lion, but can't even complete stab before being clawed to death*
*Boga bops mountain lion with club once; kills it instantly*
