If you spend it hiding, you're not getting money or xp.
If you want to be a good peasant, you have to be in the middle in the battle.
I'll reset my character, buy a shield and armor only.
Then I'll shield my archers, while looking for someone dropping his weapon.
Let's see how this works out.
Not good.
You're still just playing cannon fooder for the enemy team.
And I've reached the point where I'm stuck in Singleplayer again.
An Army of 60 men, member of the Swedian faction and nothing to do :/
I have to wait until the other nobles engage the enemy, as I am to weak to do it on my own.
Any ideas how to spead up my conquest of the nordish empire?
Hmm. As a peasant, you end up being cannon fodder for a couple hours or so. But after you get some stats and skill points you can do much better. The thing is, the best way for you to play with that mod is to group up as much as possible. Also, the newer your character, the longest the weapon you want. Stick to staves and really long weapons so you can actually help with the smacking a little bit.
As for the single player, do missions for the king or the high ups. There's always a point in single player (if you're not a CHA character) where you will be stuck with a certain number of troops. Renown wont help you that much after that point and to advance, you will need castles and cities. So you want to be given those by your rulers. So yeah, keep on sucking up, hit on the king's wife if you can so you can have her increase your standing with him later and so on.
If you can, train your troops to max and then go on picking lone enemy vassals in the map. It should increase the chances of your side starting an offensive.
