Would I ever need credit card if my debit card is issued by MasterCard/Visa?
The question should be - do you need a debit card?  Other than American Express I have to tell my other credit card issuers to not make my cards dual debit/credit. Using a debit card card can be summed up easily - It creates a risk of fraud, errors, theft, over draft, and more while providing absolutely no benefit.   It was simply a marketing scheme for card companies to reduce risk that has lost favor, although they are still used.  That is why banks put it on credit cards by default if they can. (I am talking about logical people who can control not overspending because of debit vs. credit - as it is completely illogical that you would spend more based on what kind of card you have.)
