I like to think of myself more of a predator when it comes to PK. I'm not usually the crazy crowd/mosh pit style, at least not that much anymore. I'll PK any given target I just don't like the looks of. Any given place, any given time so long as I can easily harass a person or crowd when they are given a sense of false security. Observe -> Isolate weaknesses and advantages for both sides -> Take note of skills of enemies -> Stalk -> Strike at disadvantage -> Simplify health -> Retreat to vantage point -> Stalk -> Close in -> Complete -> Repeat process.
BKs I prefer Oasis and Pyrat bay, mainly for money purposes.
