There is nothing whrong with buying skills but there are a lot of ppl who can't buy a 99 skill. So they are a bit yealous I guess and that's why they say: You've got to work for your skill and not just buy it.
It was my first day member and I was so happy! I bought gear for 1,5m (all my money) and I started some quests. I was doing a quest in jungle and a monster poisoned me, but I didn't know what to do. So I died in jungle on my first day of membership and I lost all my new gear. :(
