Nobody puts a team together to fight the PKs? Well...you try it! I'll join your team for some fun in...let's say...Hub! We'll be [temporarily] known as the "guys who fight lawlessness at Hub" and then guess what - every PK jackass in the world will start frequenting the Hub for more more more! Hub will turn into the next interesting PvP place to be and the PKs would win day after day. Know why? Not only because the bad guys outnumber the good guys, but because the game is coded such to lend itself heavily toward the worst behavior possible. I'm saying it's EASY to be a ruthless murdering PK. The big challenge is to NOT be one. Just like in RL - if you try to do something really good, nearly the entire world will oppose you.
So try getting in their heads - figure them out, don't be scared away when you realize there is diabolical brilliance in the seemingly hopeless wasteland that is their mentality. I mean, they are bad people but they are smart. Some of them have excellent vocabulary and grammar. Some have degrees. Some have really killed people for real, and some are movie star wannabes. They figure out the "game mechanics" and exploit every way to kill you dead, no questions.
Word on the street is...the developers like it this way. The idea of "newbie protection" has been rejected over and over, and it wouldn't fix much anyway. OX, i'm with ya, let's try something, but let's be realistic: we cannot win - only extend how long it takes to lose, and that's not your fault - it's the "game mechanics". Then again, maybe simply doing our best to fight them is winning. Ah definitions...
