Festival Ranking is the "festival of who will spend the most".
To be honest none is forcing ppl to spend money ,u do on your own will, like when u go at a shop and u see something and u say to yourself ..oh i wanna buy that..but none from the shop forces u to buy. NCSOFT puts on sale what they think ppl might be interested (realistic or not ,important or not ,useful or not) but they dont force anyone to buy.Tagprice for some is doable for others is not (like real life)..Should they gain more out of a sale if prices were different or if products were different..well thats another whole conversation..
