Regarding the exp it seems to me that all experience was increased to accommodate for the classes which struggled more than was necessarily to level up?
Like the combat classes seemed okay in the pre 1.1.0 however Trading, Rouge, Charm etc. seemed to level up to nearly 100 then the grind became such that the game would nearly finish with a faction taking the map or such so continuing would become pointless. So to accommodate for this they've made all exp classes gain exp faster. I started a new save with 1.1.0 Beta and have managed to reach 230 in trading after about 450 in game days which I though was nearly impossible with pre 1.1.0.
I feels like the combat classes are the ones that would need to be reduced if exp would be reduced but a lot of this comes down to the length of the game. We've got these clans and progression trees are great but it seems like the game finishes a lot faster than Warband and easier with factions taking over the map before you can even move onto your children. I believe the devs will get around to fixing this once the games a lot more patched and in later branches and can't wait but at the moment a lot of features are missed or obsolete because of how quickly the map can be taken, and just to add, yes I remembers the first week when the map would get snowballed within 20 hours of game play and that has been reduced massively! but within one characters lifetime the map can still be taken with the help of the player which is what I'm talking about which directly has an impact on how quickly characters can progress. Don't forget with the child & death system you might have to start with a new character in the game several times -generations- (thus begin the exp grind again) before you reach endgame and dominate the continent.
