Fanatacism

Looking at the guide, it says the following about Fanaticism:

Fanaticism (Orcs)

Fanaticism focuses your army on combat and war, increasing their offensive efficiency for several days. Unfortunately, a side effect of this desire for blood is that they will not be as capable of capturing land and resources, and your armies remaining at home -- bored and frustrated for not being at war -- will fight less effectively on defense.

Effect: Increases your offensive military effienciency by 5%.
Effect: Decreases your defensive military effienciency by 3%.

So in the spell description it says you have lower gains, but in the effects this is not listed. Can anyone confirm whether the combat gains are reduced by this spell?

well idk now, but it used to be like that atleast

It has lower gains, but that doesn't really matter these days, since the only race with access to it's been gifted with epic bonus gains.
