engaging as always, fellas.
Anyway. the way i see it, it's a pretty interesting concept, but i'm left with a lot more questions than answers when the explanation comes around. I'll elaborate.
Several times in the Knights of The Old Republic series it's stated that Wounds feed and are empowered by death, with each person that falls to them, they become more and more powerful. But, how does this come into play in combat? what increases? their force potential? raw power? how does this even remotely touch combative skill? more specifically, lightsaber combat.
In all of the quotes that are given to us, Kreia never really elaborates—as per uje— on how the wounds are affected by their feeding of life and death. I myself doubt it's combative prowess. all that we get is "more powerful" "strong" etcetera.
I view wounds as a force enhancing drugs, they grant you a single, deadly and destructive power(i.e Force Drain) but it comes at a risk of losing yourself to that power(Like Nihilus) I don't think being a wound and the benefit of becoming stronger with each kill is actually enough to be taken into consideration in a debate, simply because we don't know if it affects combative skill.
A great example of this is Anakin and his rival, Ferus Olin. We all know that Anakin's potential and power were great even as of AOTC and Pre-AOTC. The council and Obi-Wan during The Jedi Quest novel state this, yet Ferus, a Jedi who was stated to have an inferior connection to the force compared to Anakin, was considered to be the more skilled and talented of the two, despite Anakin's own strength and obvious power.
Anyway, those are just my two cents.
