runescape is based on luck. Most people's fortune comes from luck. Anyone who boss hunts or pk's gets money from luck. killing monsters is luck. Sometimes you hit a 30, others you hit a zero, the whole game is luck.
I would probably ask about life as a Jagex mod. Maybe ask about some future updates too, but most the time, Jmods dont enjoy talking to you if all you ask is what is coming out and when.
There is something that isnt correct here #-o #-o I didn't know f2p had 17+ skills. News to me. My total is upper 900s (i think, i can't remember and can't be bothered to check) and I've never been a member. having an extra 700 levels doesn't seem possible. Max F2p is 1494 total i believe.
