I agree, every time a couple of players (always skirmish players) speaks against throwing weapons, they get nerfed immediately. In siege mode it's totally useless to keep your distance and try to hit people with throwing weapons now (when they can easily dodge or you can miss, and even if you hit you deal low damage). You lose valuable time and valuable pressure by trying to hit with a short ranged weapon that deals least amount of damage of all ranged weapons and has fewest ammunition and is hardest to hit out of the 3... you're more useful as just going straight melee with your team, guaranteeing to hit and supporting your teammates properly.
I understand the frustration, I played captain mode as well many months ago and the meta was simply: get melee, F1 + F3 together and win by overwhelming the enemy. Not much strategy about it. I too don't understand why there is not a vision for each mode separately and a balance restricted to each. Also really no offense intended, but skirmish players did actually screw other modes directly through their complaints, even though the main fault is indeed on TW for their choice to balance all the modes together. I only played a little skirmish truth be told, but anyhow I never felt in any mode that throwing weapons were too much to handle. Dodging was not that hard to do and to me throwing weapons felt fine even when they were dealing 80+ damage per hit (throwing axes and javelin times...). Even if it really was an issue for skirmish, there is 0 reason to nerf them so much for other modes, and I just blame it on the poor suggestions skirmish players actually gave the devs (as I did see discussions between the 2). All that TW had to do was drastically reduce the number of throwing weapons they give to skirmish units, keep them on only a few units, but also keep the damn throwing weapons EFFECTIVE (which is the whole point of having such a minimal amount of ammunition AND range, they're supposed to deal bigger damage than the 30+ ammunition on the bows and crossbows with a lot more range). If you actually hit the 1-2 amount of throwing weapons you have, you should be guaranteed to do at least serious damage, period. The dev in charge of balancing should have seen through the crying of the players and actually think of a good solution rather than nerf damage to the ground, which again makes no sense gameplay-wise for the least ammo/least range weapons...
I do feel TW listens to skirmish players a lot more than anyone else, mainly because that's where the more competitive folk go and TW clearly had this dream of Bannerlord being more of an Esport. The irony though is that the most avid complainers are most likely the players that are worse at the game, because the ones better at the game are the ones that use throwing weapons effectively and also dodge and position themselves well, so even though it seems like you're listening to the "competitive playerbase" (as TWs would like), it's still the casual playerbase you're listening to, which is not good if you want to create a good competitive environment, so you're screwing on literally all the fronts. Skirmish mode needs a ranked system and players on the top should be the ones you should listen to if you do want a competitive gamemode. Still, even if you do that, the casuals will quit the game mode and a very low amount of players will actually enjoy it, so pick your poison.
Mount and blade is a niche title and it will remain a niche title, we just have to accept that and focus on making the gameplay fun, not forcefully competitive imo. I still remember the twitch streamer forsen trying the game for the first time, specifically the multiplayer archer gameplay. He basically said in the first minutes "why play this when you can play games like mordhau or chivalry" (with the pretty bland ranged gameplay bannerlord offers)... the mainstream is only impressed by shiny combat mechanics and battle intensity that fills you with adrenaline (fast-paced gameplay). Mount and blade definitely offers some unique flavor enjoyed by quite a few, but it's just not for the mainstream and will never be, which is why I feel trying to make it into an Esport and cater to the more competitive folk is truly a waste of time and more-so reduces the amount of players who would otherwise be playing the game (If you want shiny mechanics etc, you need to at least add a Sprint mechanic btw, seriously. It's 2021.). The game is not meant for the 1% of the most competitive people, even though we have a few "warband pros" that for some reason decided to become good at the game, it just won't expand more than that. There are people that get really good at the most obscure and unpopular games just to "Speedrun" them so they feel they did something in their life, yet nobody is trying to turn these janky old games into Esports... the vision for the game clearly needs a revision...
