I hate the present learning point system. Totally. When the farmer SUDDENLY draws sword, drops his 200k LP to melee fight and pwns big bad bear or robber that trespasses his farm I shit bricks.
I think that to be farmer one should harvest and plant crops and to be warrior one should fight and fight and fight.
System may be similar to FEP-system. Farmer gather crops, gets Skill Event Points and eventually rises his skill. Warrior kills someone with sword and gets Melee SEP etc:
Unarmed Combat - killing someone with bare hands
Melee Combat - killing with weapon
Marksmanship - making bow, killing with bow
Exploration - drawing maps, foraging
Stealth - at this moment I don't know how it can be trained. Maybe if it will be useful to evade meet with a boar
Sewing - tanning skin, crafting
Smithing - digging ore, crafting
Carpentry - chopping trees, crafting
Cooking - milking cows, collecting honey, crafting
Farming - harvesting and sewing
Survival - skinning, crafting.
And one other idea. Books. Master in any skill can write a book. It should be relatively expensive: for example, 2 liters of ink and 50 lists of parchment.
Reading it may take a long time or it must be red, say, ten times but there is two hour-cooldown before reading. When read, the book raises your skill to up to one-half of reader's skill that was used in book.
LP still can be useful only for learning lores and therefore it should be much more rare resource.
That's how I see.
