1: Maybe not all of them but when near a hideout I see plenty of coming and going. Maybe you are to close causing noone to leave?
2: Imho it should be more then enough to complete the quest. Had one this morning where I initially failed, went to a nearby town. Rested for a few days and came back with stronger troops. Still had like 5 days left to complete it....
3: It makes alot of sense really. If you notice what is beeing implied you have to sneak in because they will otherwise scatter to the win if a large force tries to barge in. Basicly you have to jump them because otherwise they will just run. Makes sense.
4: The game draws the units from the top first. Put your companions and/or elite soldiers at the top for this mission. Works perfectly.
5: well honestly I havent seen more then 2 dozen troops in a hide out at any given time. How the hell do you get so many bandits in there in the first place?
1: Proximity to the hideout has nothing to do with whether they leave or not. On many occasions, I have left the area of the hideout completely to return several days later, and the exact same parties with the exact same number of dudes is still just sitting there doing nothing.
2: 8-10 men is certainly enough to complete the quest if you are careful and there are only 2 dozen or less men (or so) there. However, I have seen cases where I am asked to go clear out a camp with 40-50 or more men, and none of them ever leave no matter what. Normally, you can fight the guys piecemeal, killing a handful without alerting the rest. With so many, though, (especially with mountain bandit camps) there is one part where you alert a small group and it pulls literally the rest of the map...and you can't physically get past that group without alerting them. Then a single lucky shot from the 30+ pro javelin snipers can end your quest.
3: I agree that it makes sense to have the player assault with a small group, but only if the number of bandits is limited. A camp with 50+ men isn't going to be able to just slink into the shadows. I say they should just somehow limit the number of bandits in a camp.
4: It doesn't do that perfectly. Just like in Warband, it draws troops based on an algorithm that prioritizes companions, soldiers at the top of the list, and soldiers of higher rank. Moreover, it doesn't give you a regular result, so it is at least partly randomized. I know this for a fact because when I have saved just outside a camp because it has like 45 dudes and I have to reload and try like 15 times to be able to do it, the troops it gives me are different every time even if I change nothing between attempts. The only consistency is that it seems to give you companions before giving you anything else. It doesn't always give you the guys at the top and it doesn't always give you the highest rank. I have gone to camps with the top of the list populated by like 30 tier 3+ guys and it still sometimes gives me recruits from the bottom of the list.
5: You haven't tried enough bandit camps.
