Ur competely wrong. First of all, stances are rng due to it not being controlled by you in a skirmish game, since most people already have to focus on survival and awareness alone, thus making it pretty much rng in a skirmish situation, because you gotta control ur movement based on dodging cav/arrows/throwings etc meanwhile in warband all the melee mechanics were possible to be controlled by you in battle gamemode.
About perfect blocks: they're not working with shields, therefore making them absolutely useless in skirmish except ur an archer or somehow don't have a shield (which in current meta will make you death within a few seconds anyway lol), I find it rather weird to have a mechanic that is somewhat working just in duel, while all the melee mechanics in warband would work in both: battle and duel, besides as I mentioned in my original message regarding them, they're absolutely buggy at this point, recently I've been trying to basically just perfect block on the duel server and the amount of my hits not registered at all or delayed were absolutely insane, around 60%, idk what's causing it though: the perfect block themselves or ****ty TW servers
