There are a few people I die to alot, I do tend to see the same names over and over. But there are just a few who I consider "adversaries". In my book an "Adversary" or "sworn enemy" in a game is a person who I really like.
I enjoy fighting nice people much more then a-holes. I can devote alot of energy and comitment to fight people who I really like because its always fun. Fighting a-holes isnt and gaming is about fun so I just ignore them.
In Jumpgate I had my blood sworn enemy in a guy called Russian (not the same guy as Russian here). We constantly tried to outsmart each other and beat each other. At one time our two squads where flying together because we where good friends but the we realized we missed fighting each other so we delcared war on each others squads.

So far the closes to an adversary Ive got in AH2 is Redd.
I really enjoy fighting him I tend to run into him everywhere and die to him. Redd has helped me alot in DA and over mail and is a top notch great guy.
I actually do recognize him in the skies just through his fight style and each time I see him its like... "butter its Redd... stay smart stay smart... CRAP NOT AGAIN!!!!!"....
For me its much more important to have guys like that on the enemy side then have all the nice people on one side... because if all the nice people where flying on the same side and all the a-holes on the other then I would not be playing the game... there wouldnt be any laugh, joy and no fun in the fights....
Great people on Knight and Bish side of the fence...
