I'm also starting to wonder if I should just use OBMM or even NMM over Vortex for Oblivion.
I have Oblivion set up using WryeBash
Because Oblivion is such a complete Pain in the ass to Mod, I have no intention of moving it over to Vortex, as much as I like Vortex.
Because Oblviion really NEEDS the Special tags built into WryeBash to build Bashed Patches properly.
Same with Morrowind, I'm leaving both of those out of the picture.
