Why are some wild creature armies so extremely powerful?
I understand that the point of having wild creatures that aren't part of any faction is to make the game a bit more challenging even when you aren't at war with any factions, but why do some (not many, but some) armies have these super powerful units in them? Wild creature armies should not be more powerful then whole armies from other kingdoms!
For example, I had spent many hours defeating a darkling army after darkling army with no problems, and then my army entered this desert area that contained an army of some creatures called "Wildings" or something like that. In that army were 3 units called something along the lines of "Wilding Shamans" or something.
"No prob, I got a 7 unit army with decent units and a fairly powerful mage" I thought, so I attacked it...
...then literally on the first turn of combat those 3 Wildling Shamans used some special ability called "Coal stones" that send fires throughout the whole map 3 times in a row and killed something like half of my whole army.
What? Just....what?
I mean I wasn't even able to do anything, there was NOTHNG that I could do other then just stand there and watch half of my army burn into crisp.
I tried to defeat the army before those Shamans could use their special ability again but it failed, so the second time they used it it killed the rest of my army.
During later battles I took a couple of archers with me and targeted the Shamans to kill them before they could use the Coal stones ability a second time, but even though this allows me to win battles against them they are still able to use it at least once at the start so even then I still end up loosing most of my army. It just isn't fair.
So why are these guys so powerful? It doesn't seem fair to me that I can lose half of my army on the first turn before I can even move...
