Do you always get 1 xp for surviving a battle or only with some scenarios? I didn't get it in my last game it I had been getting it previously.
It's based on the scenarios. Some do, some don't. Some give you XP for getting wyrdstone. The only guaranteed XP is 1 for the leader if you win, and 1 for each kill.
My experience is warband with lower rating don't give survival bonus for missions not sure if it's 100% accurate but that's how it seems to me
That's not correct at all. It's purely down to the missions. If your warband rating is sufficiently low you get extra XP with the underdog bonus.
I think there should be: #1 experience of taking enemies out-of-action #2 experience for not being taken out-of-action #3 Experience for winning #4 Experience for claiming secondary objectives such as getting into the enemy base.
AND, you have a lower chance to roll "dead" on the injury table (unless they reverted that incognito at some point).
It also seems wierd that your guys are always just "out of commission* yet you see the results instantly, (Dead, Injured, Knocked out) I get that it's a dice roll after but the game seems to calculate it when it happens.
I mean it might be calculating instantly for your warband too you just don't know. Also its not like your gonna see that war band again most likely.
So what missions give you xp? I had 4 matches yesterday with no xp for my low level guys who didn't kill anything
