I think I'm a combination of B and A, but mostly B. My main problem is I don't main security, it's something I hop in when I feel like it, as I will often play detective or pod pilot. I'm rarely a security patrol officer, preferring the flexibility that pod pilot allows me. If I was going to pick out my main weakness, it's remembering the sentencing caveats of space law and such.
Very much a talker though. Prefer to chat with potential crims first, very much hate the mentality of tasering first and questions later. There are exceptions to this; dangerous EoC's that are obviously not going to sit and chat with you, and in those situations, shooting first is your best best.
Also surprised the highlight string didn't get a mention in any of the tiers (mainly the upper ones). I deem the chat highlight function to be essential on a high pop round. Anytime I'm going poddy/detective, I'll put keywords like 'detective pod pilot security hos Head Security help death alarm' and vice versa in there because the chat does be whizzing by and it really helps filter out the noise. Also if you know what kind of antags you are dealing with, putting them in the string helps!
