That some players that prefer PvP are frustrated is understandable - however their preferred play-style does not force others to play the same way.
I've had these issues before I ever started PVP'ing in Elite. Maybe I have a more of a PVP mind set in general, but I think it is more about wanting a multiplayer online game that makes sense. Talk about immersion breaking mechanics, this has got to be one of the top ones for me. And was the reason I decided not to get involved in Power Play at the beginning of the year.
When it first "clicked" for me how all of this worked I was dumbfounded. And I still am, to be honest.
