I agree, better min damage on melee for more consistent damage, better potential damage on ranged.
I like the idea of scopes being useless for melee/ma - that would be appropriate. Give non-ma ma users something to compensate though, something like the vision enhancer but with increased init penalties for ranged and reduced for physical (and maybe melee too?).
Add a small crit boost to the rage line of nanos (1-3%) would compensate for enforcers to some extent, that ontop of flurry should be pretty decent. Don't know what you'd do for adventurers though...
And as a 1he user, I'd vote to get rid of the HW contribution to AR too (or at least reduce how much it contributes), not related I know, but...
