I see every other race has both racial passive and racial active power, but why orcs only have a power and no passive?

Because they have a better power.

Because their power has two effects, and is pretty powerful in its own right. Berserk is basically just a [censored] you button for boss fights, they may as well just rename it, 'I Win'.

I noticed that too. I hope it's just lack of info.

Orc racial is overpowered as [censored], it basiclly improves your combat power by 400% and allows you to kill anything

Their passive power is to look awesome and posess the best racial power of them all.

When they say half damage, do they mean all kind of damage? Both physical & magical even falling damage?
