Question: can qss cancel morde ult?
Answer: Qss will cleanse that cc which terminates his ult. The role of Morde in a team fight is not to kill the adc specifically. ... - if Morde ults the adc then he is forcing the adc to use up his qss which could open up engages from other champs, for example, Morde ult followed by Sejuani ult.
