Fair enough! There's at least one modder that apparently figured it out. I'm using both mods together and just tweaked the 2da to re-enable the (now significantly nerfed) energy resistance and speed powers back. Not sure how Elm did it, but I can verify it works as described. Here's the mod.
Liking the changes and running the mod now. Any chance of just nerfing knight and master speed? Give knight speed an attack bonus, and give master speed an extra attack? I know this is hard to do, but it looks like a few modders have done similar -- at least for TSL.
