So how is DWing pets working on green?
 

Is it like on blue? You still need to weaponize charms, but regular pets DW by themselves if high enough?

Yes it's working the same.

Shouldn't be, you should always need to give weapons to charm/necro pets until January 2000, and mage pets shouldn't equip weapons until then either, and hence shouldn't dual wield yet at all.

Maybe for Green 2.0
