These formulas are not shown to public but wowhead thinks, they look something like this
(Attack Power + Weapon DPS * 6) * AP Coefficient * Damage Multiplier
Which is a fairly easy one to work around with^^ (you can search article on wowhead "formula for calculating ability damage")
Now since we are moving away from spec design
They HAVE TO make brewmaster abilities (2h) work for windwalker (duelwield) and visa versa. Since they are making 2 formulas for most of the class abilities, they probably thought like, "well, we might as well scale these remaining ones too, to give players a choise". Which is seriously awesome of them!
But since enhancement only has 1 kind of melee dps spec, abilities were never made to scale around for 2h during legion. This is the only reason i can think of why they are not giving us 2h.
All damage formulas for death knights, monks and hunters (most probably warriors too) are being updated to work with both 2h weapons and duel wielding for this business. They are excluding enhancement because its too much of a hassle.
It's now or never guys. We have to make them know we want it bad. This is the only expansion they decided to listen to players.
