Alright, I usually never post for anything, but putting down a few ideas couldn't hurt too much.
One thing, I am sorry if these have been repeated already, and if they have there is no need to read the entire thing, however there are some tidbits that may be found interesting. Furthermore sorry for this wall of text
Minor Thoughts
Shortening the time it takes to change classes would be a nice improvement, so people do not have to hold down the same button for a minute waiting to become a man-at-arms, or doctor. I see little way in which this could be abused, besides the fact wasting your money very quickly for someone who doesn't know which class to stay as.
As a serf, or what have you, when you are chopping a tree down or mining a rock, having a small chance to recieve something extra. By extra I mean small resources that would be used for different classes. For example a special herb or piece of bark falling from a tree while you are cutting it which could be used by a doctor (to create a special "item" to cure poison or even beable to poison a player by itself, or engineer (to craft things similiar to poisoned daggers maybe, or weird things like historic "glue" for crafting a new weapon or what have you).
Another small thing to chew on, how about buckets that can actually do something besides being eye candy (having wells that actually work for water, possibly? which then could be used for something like, spawning a tree faster? or something of that nature).
Having the ability to sell arrows, instead of having to drop them when selling back a bow. (Same with Crossbow bolts).
More Realistic falls, I find it hard to believe that when i jump from a roof in, lets say, scene 3 and land on a piece of wood before i hit the ground that i take no damage what-so-ever, or when I hit a step slightly higher than the one below it and have drastic damage differences.
More simple weapons, for example rocks maybe? since sticks already exist, and so on. But something that an everyday peasant would have access to, like a pitchfork or a wheat scythe.
I'm sure that the "weird" weapons were gotten rid of for a reason (as in throwable fish, or cups, etc.) but personally i thought that added a bit more realism to the game itself, what better way than to celebrate with your faction then go to a pub and but a "cup of grog."
Something about the horses, as i'm sure its atleast happened to someone at some time or another where you tap F and you by like two horses instead of one. Something that could possibly sell horses would be nice, even if its half the price you bought it for.
Faction color text based on the banner seems somewhat annoying at times, especially some banners in particular which are too dark and can become hard to read, when you type in faction chat. However i know that would take a bit more tweaking than most, but have an option to choose between like six colors? Red, Green, White, Black, Blue, Purple, Orange/Yellow/Tan?
Having a solution for carts being in the middle of the high seas would be nice as well, since some can actually stop a boat. I know one in the current map which you have to steer around it so your boat doesn't get caught by a little wheelbarrow, (Not sure if you can truley do that much about it though).
This one I have second thoughts about, since engineers usually don't keep up with mass resources serfs produce, but No merchant in their right mind would by 2k+ Iron ore for the same price contually, unless he had the best deal on the planet to sell them. (I'm talking about the stock piles of wood, iron, etc. which are usually either really high or non-existent in certain castles/cities) What i'm trying to say is that supply and demand, you grind and mine 200 iron ore, but you sell them for all the same rpice, which i find hard to believe, then again they are "stock piles".
Major Thoughts
Having armories moved inside a faction's base, so that "common folk" don't have direct access to them, since normally a mercenary will not have as good arnments than a already set military soldier. So instead of having every weapon spread across the street, having them in the walls of a faction's castle as their own private arsenal, and you could make it an openable door, so non-faction members can still get the best weapons, but would have to RP their way into the armory.
Bandits/Outlaws having better spawn points on some maps, since the maps I've played all seem to have the Outlaw's spawn all the way in the middle of no-man's land where there are no horses to buy, without walking for an extra five minutes until you reach a deserted village. I like how that bandits have worse weapons than real soldiers and mercenaries, but i sometimes find their stats lacking, when all they have to choose from is huntsman or brigand, neither of them able to wield powerful weapons they could scavenge from a well placed ambush. Though I like the fact that their skills vary slightly, more roundness than a specialist.
Some type of area where people can go vent off steam would be nice, so that randomers, or future randomer's could go do their mass killings of people in the appropiate envirernment, such as an arena, where you could spawn in possibly. Making it a spawn point to choose from the beginning.
