1) Are elves supposed to be in kind of semi-alliance with dwarves? Playing a Rivendell Elf, I can enter dwarven towns normally but when I meet their parties on the map I can only fight them. I can get a quest from a dwarven lord while he is in a town, but if he goes out I can't tell him I completed it until he goes to a town. Another thing I noticed is that dwarves end up as prisoners when I rescue them.
2) There is a similar situation between the evil factions and neutrals/bandits/outlaws/outcasts. The neutrals are hostile to the evil player but not to any of the evil factions. When there is a large battle between good and evil guys, the neutrals can take place on the evil side, but the player will be unable to join if the neutrals were one of the sides that started the battle.
3) While playing as an Uruk, the morale of my party went low and I got constant mutinies by orcs, requiring me to defeat a rather powerful orc in a duel or lose most of my party. I didn't notice this while playing as an orc even though my morale went low in with that character as well. Do mutinies happen only to Uruk player with orcs in the party? Would it help to not recruit orcs? Do goblins mutiny as well? The duel is very difficult at lower levels and I would really like to avoid it.
orcs have their ways with their kin, so lower chance of mutiny. If you are weak and attempt to command many orcs, they will more likely challenge your command
