On a humorous note, you can save edit as the saves are held in notepad form iirc, and you can crank your Agility well beyond what's normally possible, allowing you to run faster than a horse, and because M&B uses velocity as a modifier, you can deliver bare-fisted punches that hit like a meteor and will OHKO knights in full plate.
With the flip side of this being the Rhodoks (Green bois) are also terribly weak overall until they start vomiting out Sergeants, which just wreck face in seiges on defence because crossbows fire slower and thus are still firing later in a seige when everyone's still on the ladder (and Sergeants don't just have polearms, removing Rhodok's crippling weakness of being absolutely out-damaged at dagger range by anything short of fists) Khergits are somewhat shafted as they're terrible in seiges but since the 'point' of the game is you can mix and match it's not *really* a problem, but I do like to do thematic runs. Yeah Vanilla's fun too, I think I do have one mod that overhauls it but keeps it largely vanilla, just rebalancing some stuff.
