So I recently came out of a 1.5 year retirement to find the world much changed and I am in need of your assistance. I just recently joined the p2p worlds and pvp has always intrigued me: however, observing some matches and these forums have led me to the sound conclusion that I would get destroyed in my current state. My questions are as follow, 1) Is there any way for me to become a decent PK'er, my stats are in siggy and I was looking more into range tank but I couldn't find to much info. 2) If it was yes to part one and I can PK say as a range tank what equip, short term goals and long term goals am I looking into? 3) Any advice as to how it all functions now since it would appear everything is way different then it used to be. (Basically whats going on) 4) Please share any other helpful hints and such -Thanks Zane
