ontop of that if you just keep clicking left button it automatically start to initiate the next *fastest* swing based on the last animation or direction you were attacking. I don't think you even have to pick a direction. So most people are just clicking and swinging constantly mindlessly. Thats why you'll see a lot of LEFT then RIGHT then LEFT then RIGHT attacks from noobie doobies.
Then you have the chained attacks swing where after you swing you hold the button and choose the next swing direction you get a different animation which I'm not sure if it speeds up the wait inbetween regular attacks.
Bigger difference most people will probably notices from warband to bannerlord is that your positioning is going to matter more because you can't initiate blocks sometimes as fast due to the way the animations work.
Bannerlord's foot stances (which I've yet to really test) which can speed up your attack or make your defense better based on your foot position. I can't find the video of this anymore and the beta forums gone where people were talking about it.
Only examples I notice if you have 2H or spear you can initiate a stab on either left or right side of your character. Also I guess if you have for example your left foot forward with 1H and do a left to right it might be faster versus if you had your right foot forward and do a left to right swing. I've yet to really pay attention to this, but due to the fact blocking takes a little more time to move our hand to the position to block it might mean you have to pay more attention to this.
I've gotten use to it, but can't really say if I like Bannerlord's system more or less.
