Ava's good at sneaking around in the woods. Cause, you know, she was born into an environment and society where doing so was of benefit, so she became very, very good at it. Middle of the boreal forest in the dead of winter? You're simply not going to find Ava unless she wants to be found. Take her out of that environment, and she's suddenly pretty ineffective. She's learned a narrow range of things. Dropping TERMINATOR GODMAN 9000 into this environment and having him be more effective at it than those people who have lived their whole lives there is problematic for me, especially as they tend to ignore things which are sorta important; do they have a VERY good explanation for "why do I and my 400kg robot mass not sink into several meters of snow, or fall through the ice and die?" This is what annoys the shit out of me. I have, in the past, seen people just say "My character is cybornetically enhanced!" as an "I will always win at any scenario" godmodding tool. That just irritates me.
I see Khanid cyber knights as the same in most ways; good at a narrow range of things, specialised at those things, and not good at EVERYTHING. Had i not started with minnies, a cybernight is almost certainly what I'd explore, because its cool as hell. I dont think any of them are one woman/man walking marine divisions capable of destroying all in every scenario. I picture them much as Silas described; among the best in their element. Not so good outside of it. They have learned a narrow range of things, and then improved them with cybornetics.
I dont see cybornetics as a "insta plug it in and boom! Godlike warrior!". I see them as being used to enhance what the person already does; it is augmentations, not a crutch. I deeply enjoy out of pod RP, as it simply appeals more for me. Some other people are the same. I dont mind RPing with cybornetic people who are like the 2nd one. I deeply mind the TERMINATORGODMAN9000 types.
