I'm almost a little backwards in my decision.... Sure, I chose Marksman, but in the aspect of the stealth side of it....
Say, for example...
Shooting someone in a camp from about 3 miles away with a sniper is fun... But the more entertaining side of it, to me, is if said sniper was silenced.... Therefore I find it to be a challenge to take out as many guards as possible, before they found out something was killing them..... That, and, I figure I want as much distance as possible between me, and the things that want me dead....
Now, my point in how this is backwards, I know that this is a single-player question, and that's how I answered it.... I love standing back and being the subtle helper in a fight... Whereas, in a multi-player game I hate snipers to death, as if it spoils the concept of the game... (What that is, I don't know)
I guess it's because the essence of "camping" doesn't exist in SP, so you can sit there all day and just snipe people happy....
But other than that, I'm a marksman/stealth (if distance isn't an option)
