It would mean that any channeler characters would be either, if female, restricted by the Three Oaths (or if you also have the Wise One / Sea Folk channeler options, no Three Oaths but far more limited possibilities), or, if male, would develop slowly and be prone to uncontrolled outbursts that can harm your own group.
Also, I'd say a separate story that intertwines with the plot of the series but doesn't follow it might be better.
This makes me wonder if anyone ever played the actual WoT video game they made 20 years ago? It definitely wasn't a BG style game, more an action RPG/shooter type game, but I never played it.
