I used to play Mordheim: CotD years ago.. despite all it's shortcomings
I really liked that game but (iirc) it was sadly abandoned by the devs when they started developing Necromunda: Underhive Wars. I'm not sure if they continued working on it, after the latter was released so my opinion might be outdated.
- Game balance was a bit of a mess. The undead warband (DLC) was clearly op compared to the others and you would play against them, (even in single player) even if you didn't have the dlc*. With proper tactics/luck you could win against them but it was difficult especially at low levels.
*Same applies to the witch hunters, but they were quite balanced.
- Likewise some builds were not viable. For example, judging by their innate skill, human captains are supposed to be played as "parry" tanks which works great..until you encounter one of the enemies that completely bypass "parries".
- Game performance is wonky and it seems to be affected by how long you've played with your current warband. Granted my pc's specs at the time were somewhere between the minimum and recommended, but I've noticed, consistently, that as a warband grew older/leveled up, enemy turns would take longer and longer, to the point that the game would effectively "freeze"** and you had to restart it.
** The game wasn't crashing, but it's turn based and you were practically locked while the enemy made his move which he didn't so.. yeah doesn't matter
