Liadon. I have also hunted with you on several characters 
You definitely need to work on your speed when it comes to things happening in combat. IE, being disarmed, allies needing healing or sanctuary, sleeping right before the hour passes to do as we call "catching a tick" etc...
While a Herald Healer is a great character for stimulating RP, it is not gong to help you learn to pk much at all. And as some people pointed out, gate will spoil you when it comes to learning how to get around on foot. You will get used to gating around and having near pk immunity. Then some nasty syndicate will come along and ruin your day. Blasphemy is not the only thing that prevents gating, and there are many ways to blind people in this game.
You are still very new so do not be discouraged! You are doing great, but you might want to think about having an evil melee/rogue on the side to keep your combat prowess coming along too. A throwaway character that you can die learning on. From what I've seen I bet a side project for you would still be very well rped, but it would give you a chance to work on the part of you game that is less developed (if you desire more than being great at RPer that is).
