it does take just one character to get into the flow of being a decent PKer. provided, that is, that said player does his homework (i.e. reviewing logs, finding why you lost and why your foe won, knowing the lands backwards and forwards, researching items, researching classes, researching races, changing tactics, adapting to enemy tactics, learning how to chase effectively, knowing when to flee... i could go on and on) and actually putting time and effort into developing and improving yourself in the PK aspect.
problem is, a lot of people do not want to do this. they want to go from suck to sugar instantly. and when they don't, they tend to shift the blame from themselves to something else. nothing is free. you need to earn it.
i learned like this. my first character made it to 50 and got into Savants. i got trounced from one end of the land to the other by Grishnak and his WM horde. i died many times. but you know what? i took it in stride, did the neccessary homework, and bingo, i saw improvement on THAT character. i started to hold my own more and more during each encounter. i learned how to run, i learned how to re-equip effectively and timely. at the end of that character's life, i beat Kentry one on one. for a complete noob at the time, to beat a very good player (Auzzie has mad skills) something about what i'm saying must be true. and from then on, i applied those new found skills to each new character i made. it was because of losing and losing big time, that helped me have multiple triple digit kill characters.
i've said this many times before on old forums (right, Tymox?). YOU WILL DIE. SUCK IT UP AND LEARN FROM IT. NOTHING IS FREE. YOU GET WHAT YOU PUT IN.
