Yup, if you have a higher rank then you'll usually be the one targeted first lol - newbies enjoy the fact that they will inflict more damage to you!
Personally - I always judge according to who played well, or not... the dumbest players I kill first, and the smartest last... their rank doesn't matter at all.
I try to avoid alliances - so I don't feel betrayed when someone attacks me... as long as it was a good move that didn't just hand the game over to another player lol!
