Wind Archer gonna had a hard time with DR-bosses.

Psh, Trifling Whim got nothing on Soul Seeker.

This, but the reason why I say that is mainly due to the fact that if you don't know the timing of DR, or if you just attack blindly like this guy did on his second death, since it was obvious DR was still up when he attacked her. I loved the o.o? he did after the second death, but yeah as others have said it is all about timing, if you don't know the timing you will die, simple as that.
