Orcs – discussion about the race.

Well, how can you protect yourself from mind control when facing a Berserker? Are there any ways to do it?

And another question,
Is 1 attack point a lot? And how much is it?
I'm interested in evaluating whether +1 attack for Garuna over 6 levels is normal or not.

Antimagic is needed... And also, I think you should split the strongest Orcish unit (most likely, Cyclops) into two. Then one will be temporarily disabled (here you can only reduce the probability of this with barbarian luck and artifacts), and the other will be able to act. Yes, I also actively use goblin sorcerers; a 50% chance of a spell not working is not bad at all in your case.
1 attack point, in my opinion, is very little... For the difference to be noticeable, it should be 5 points, at least. For it to affect the outcome of the battle, it should be 10, otherwise it is unlikely to change the result.

And Orcs' attack already grows normally, so I don't see the point in +5 attack for 30 levels.
