[Snake]

Maybe even like:
Cobra stance:
Rank*10 Evade from front and halved from other sides? So it´s getting a better friend of dodge people that don´t entirely rely on buffs?

Not needed, we already have GUI and Flanking for that.

It seems you didn't read well about Snake Dancer, Snake Dancer is what allows the Cobra Stance to dodge autohits and magic, so let me clarify.

It goes up to Rank * 2, it's going to give +15 Evade per rank. (Up to +30 Evade for having Cobra Stance on, while having Snake Dancer in your skill pool, the 'dodges' that once were capped at 2, are now 'infinite' like Kinu's Snake Dancer, because you have Evasion check to balance it.)

So if you suggest to lower the dodge from the sides and back, the Evade buff is going to be pointless, if we put something like Flanking, which already gives you bonus Hit for attacking on the enemy's sides and back. (Plus Snake Dancer not activating along the lines, because the attack is not head-on.) (Plus-Plus, I think Flanking also applies to Autohits and Magic, so here's it.)

So I suggest to not add anything special to it and stick to the simple +30 Evade.
