Hint : strellan doesn't charge and spends his/her life farming rps, or reading big5 sourcecode to understand how it works and firefox debugger to see what the price of items are to get them in 4/5 shots. He/She doesn't know what the word "charge" means.
He/She doesn't also understand we all have a life hence why we don't spend our time 24/24 on Rohan and have to charge to buy anything.
