Persuasion is an easy access skill for high will character a.k.a Psionics.
Psionics are already very strong, do they really need to be efficient whith talking as well ? And they are also the only efficient character with this skill, because I don't see any build with high will that would not be a psionic.
As a result, efficient Persuasion char are only psionic. To remedy that, I think a similar system as melee would be nice.
Either intel or will could be use for this skill.
