I've seen several "guides" saying to do different things with gems. One says to use hybrid off-stat gems (exp/hit) in red slots instead of pure int. Is this correct? I know you get double secondary stats when compared to int, but you can reforge for secondary stats where as there's nowhere else to get int from but gems/enchants. It seems counter-intuitive to me.
p.s. If it matters, I'm asking for fire spec.
