So I disagree with a lot of what OP says. Granted I'm not playing in competitive custom lobbies or whatever you guys are doing, I'm just playing skirmish.
I've played a few thousand hours of warband prior to bannerlord.
1) "Shield Bash seems to do nothing" I've really enjoyed using the shield bash as spear infantry, great to reestablish distance.
2) "Archers are too accurate" I've noticed a huge difference here over Warband, most of which I've attributed to better networking. In Warband, if you had 90 ping, your arrows had a massive delay before being fired, here that delay doesn't seem to exist even on 100+ ping, resulting in many more competitive archers. "-don't like how there's barely an arrow drop" Most of the maps in skirmish don't have long sight lines that result in a lot of arrow drop.
3) Most of the other problems described speak to "It's not warband pvp" and it's not and it shouldn't be.
4)Chambers are fine and dandy, but being able to chamber every swing consistently, leads to people not swinging. I agree that chambers should be overall be made easier, but still maintain a high amount of risk when attempting.
5)"Movement feels floaty" Movement to me feels way more fluid than Warband, aside from virtually no jump stun on landing, I have no complaints about it.
6) "blocking will be good once you can block 2 opponents" What, no. You can already block 2 opponents, it mostly comes down to swing timing from the 2 which is how it should be. If they both swing at the same time in different directions you're not blocking **** and you shouldn't be able to unless you have a shield.
7)" classes and perks are unbalanced (who would play a peasant with bad weapons and armor?) " I see reasons to do it, round 1 in skirmish you start with 300 gold, if you pick a Peasant for 3 lives you get an extra re-spawn.
" throwing weapons do too much damage " Disagree completely. 3-4 javelins to kill an armored opponent in skirmish (without headshots) is fine and maybe not enough damage. Throwing axes seem to do a lot though.
9) "handling cav still awful feels like ice-skating " ARE YOU INSANE? Cavalry to me has felt way better than Warband.
And now all the stuff we're complaining was in Warband, but is different in Bannerlord and is irrelevant. Different games.
bump-stabs need to be more easy to do
infantry spears need to be shorter
bump couching is too easy needs to be looked into
The 3rd person cross hair placement is really counter intuitive, and should be made similar to how warband's worked.
TL;DR
I hope they don't change most of the core aspects of pvp right now.
I would love to see more customization. But we'll all probably only be playing mods for pvp a month from now so who cares.
