its situational almost. but its not for damage its for cc. you can 12 second blind someone or blind two people for 8 seconds with a 8 sec gap between the two. You can 9 sec kidney 1 person or 6 second kidney two people. possibilities are endless. But its not for damage at all.
Shadow reflection with Sub or Sin actually does decent damage though.
I see, so how exactly do you go about 9 sec kidney someone? Doesnt it DR?
