Will it be better if it look like this:
In 1st stage, she (Profit-Taker) only circles between 3 physical damage types (IPS), and raw elemental damage. (Fire, Toxin....) = 7 Damage types
If you hit her with combined elemental damage, it will reduce by half.
In 2nd stage (4 min countdown), she only circles between combined elemental dmg. type (Rad, Viral...) = 8 Damage types
For Arch-Gun Cooldown: Every times she does ground slam (Magnetic wave), it should also act as an EMP that reduce Arch-Gun cooldown by half.
If anything above doesn't make any sense, please be gentle to me >_<
