Been playing for about a month, mostly co-op to "get my sea legs". I normally approach the game the same way every time (depending on class, of course) but find my results all over the map. One game I'll kill 4+, the next I'm the first one down with not a shot fired. The next, top of the leader board again. Is it just bad luck or what? If I'd be changing up what I do and how I could see reasoning for such a large contrast, but this baffles me.
Anyway, I try to do a little bit of this, and a little bit of that with all classes. Don't really have a favorite or a least favorite, they're all great in their own ways and they all aren't so great in their own ways. End-of-the-day though, I have fun 90% of the time, which is to say it's a good thing. Keep on keepin' on, and have a may your evening skies always be red.
