Mir's renowned for its pvp and probably always will be, and when fighting is one of the main reasons people play you're bound to get people who take it seriously and get competitive. That being said, it's always nice to come across a non-hostile group of players or guild who are just hunting for the sake of hunting and aren't gonna try anything the moment you come on screen.
For me, I'll be playing mainly for the pvp aspect as that's part of what makes mir unique for me compared to other games - the game isn't too complex, you know roughly where you stand when you pick a class, and fighting feels so 'connected'. Dropping someone who just tried to pk you and seeing the contents of their bag appear all over the floor is quite satisfying.
For an analagy, mir's a bit like driving a caterham vs a nissan gtr. Both are designed to do the same thing, just in the caterham you really feel like you're driving, and you can feel everything the car is telling you, rather than sort of floating round the track with all the fun taken out of it because it's almost too easy to drive.
