I have Nightmaher and let me tell you - she can, and does pull her weight. Her skill set is very well put togather, she has all the right tools for the job, and many times she was the last girl standing in her team chipping at the Boss until she took it down. Granted Anewaifu is always a solid choice for counter, although with the changes to her it seems they are trying hard to push her into the Crit department.
