Easily the best woman combo is WW 600+ Batgirl Prime and a carry. I preffer arkham knight catwoman just bcs she has a huge 1v3 potential.
This is how the combo works: WW gives all females characters 30% more power regen and attack dmg. Batgirl lets your *carry* starts with 1 special chrage and with WW passive she can charge special 2 with 2 attacks or so. If your carry is Catwoman her bleed is amplified by the WW passive. Also you can stack the bleed with WW special 2 attack. The gears are pretty generic and for catwoman i would reccomand the fourth world set or the league of assasin set. The foruth world gives a more sustain playstyle and the league gears gives a more offensive playstyle. You can put catwoman first character for instant burst but if the enemy team has the motherbox gear its a huge counter so i recomand putting WW first character and give to her more tanky gears.
