I agree, there's a lot to rebalance and I'd love to get on it right away. However, I'm back at the office and 0.8 has been delayed enough already. I should try to get the bugs under control (the game is going berserk on me since I added PBOD) and get the release out. I can always adjust quest-specific rewards for 0.9 or put them in a 0.81 patch. (I have some in mind myself, e.g. the "get the debt back" quest which often yields 0 money and very little XP.)
As for the "invading armies" and "more bandit types": There's already a bunch of bandit types (check the troop tree). The problem is the spawning. I have yet to figure out how that's done and how I can make it spawn more types. As for the invading armies... It would be pointless if they behave like regular bandits. And if they are to be completely different in style and behavior that's a big one. I think this should first be approached in a mod, not a mod pack. The same goes for a larger map. If Neo Native expands the map, I'll gladly try to merge it into the pack, but a project like that should be driven by a mod.
I might look into the caravan tribute as it would make sense to adjust this the same way as the tribute from the player to bandits.
It seems inappropriately complicated to make the kidnappers keep the money so you can steal it back, since the loot calculation is completly seperate from the quest scripts and it would probably need a global variable or something for that - I dunno. Simply don't pay them in the first place.
Firstkill, I think we had a misunderstanding: Hussars have a good horse, strong armor, a special lance, a decent sabre and a pistol. There really isn't much else I can do for them! Also, it's not possible to ensure that they spawn with lance AND sabre. Unlike for ranged weapons, there is no flag that guarantees different types of melee weapons to be assigned.
The gatling pistol (and some other controversial items) won't be available in 0.8 any more as they don't fit into the original (historical) theme of the game.
Edit:
@Kmdr Mumm: Taleworlds didn't do anything wrong, Warband is an awesome game. It's Sich who made this mediocre mod called WFAS. That's also the reason why it's not allowed to port Warband stuff to WFAS - with the obvious exception of mod content which is owned by the modders.
