Does going in a team the boss Scarlett Etzel decrease the chance of looting cobra items?

Question

Since the boss drop is based on damage and participation, when you go to kill her with other people, because your damage is reduced, the chances of you dropping rarer items is more difficult? Or is the chance the same whether you go alone or with someone?

I suggest to make some reaserch first to avoid duplication of already existing questions.
