You know I was reading this and well not all of it just OP and I wanted to just touch a few things quickly. (even if it has been said before)
Where my point is coming from: I played Ultima online Pre-Eagames and After Eagames took over. I was known as Galad the looter (so I was a pvp/pker, I also belong and lead the largest PK/PVP guild in UO "Fallen Lords") I've been in the middle of a 40 vs 40 , 1 vs 10 10 vs 1 even 1 vs 20 (1 begin me) .
To the Point:
I have seen pvping in all sides, and I'll say this there is NEVER a short supply of people to kill, either it be your allies, friends random joe carrying that 5M gold deed, or even the new guy who just got his house and you killed for his house key and waitied for him to logon and kill him inside his own house and loot it in front of him (bwahah)
People will always E-peen, whine, cry and even Ragequit hell, I've seen someone toss his monitor for getting killed one too many times. In this type of game, Teamwork is critical ! You need friends, Crafters, Pvpers, Guards, Nabors whom you have good relationship with. It all works together, and if you are the poor smuck that is getting killed over nad over and over by that asshole up the hill from your tribe's location. I promise you there is always some big shot asshole who he thinks is king shit that will defend you because his roleplaying ways tell him to.
On and ending note: I don't hate you roleplayers but I sure love killing you more than anyone else. ^_^
