@arkandel I have given a bit of thought to a WoT (and homebrew) setting using Evennia, but it would require a considerable time investment in the coding because I would want a channeling system that works based on implications from the books. (Some weaves are implied to be composed of parts that serve a function, such as Romanda thinking that the weave for detecting male channeling resembled the one for testing for resonance, suggesting that certain formulations of the Power do similar things. Another sister comments that Rand's use of saidar at the taint cleansing made no sense, suggesting there is a building block for how weaves work.)
The tl;dr of the system would be something kind of alchemical. You are taught/learned basic parts and weaves are a specific permutation of those parts, and the sum total requires a certain amount of the Power and/or Flow strength.
I would be absolutely wretched at running a game though. I know myself well enough that I would have a hard time dealing with the myriad issues.
