Thanks for the feedback.
I agree that K is essential in PK. It's still fun when you kick someone's ass and they get away, but there's an unsatisfying feeling that goes with it.
I thought flyto/murder would help with sealing kills. I think I've personally had more problem with shifters than transmuters, at least at hero-range.
I did think about doing a tranny, especially a sneaky tranny. I thought they were more for exploring.
Do transmuters rely on low save vs. paralysis for kills? Can they solo-PK above mid-ranks?
