Just wanted to add my thoughts. Starting in Beta I got Karthus and fell in love for banishments. When I first started using her for PvP, I wasn't impressed. Seeing as I am a bit lazy and didn't have another hero with full upgraded equipment and runes, I started playing around with her to leave her in formation full time. Since then I have also gotten Shayd on Beta and I run both, full time. I also finally got Shayd on live server and she is a full time hero. Her hit rating isn't the best, but I get more stuns from her then I see Cianna get. The runes I try to use are Vitality, Intenseness, Preciseness, and Nimbleness. I am also currently trying a Burliness in Beta since she can be very frail. I find that, formation being key, she can take a beating, dodge a good bit, and when she does hit cause destruction. I am working on my live Shayd, but both my Beta girls hit for around 15K-18K. Just my thoughts on the matter...
