As many people have already said, I'm just going to reiterate it...
Plat is supposed to be to provide an advantage to people who WANT to buy it, to speed the process up. In this case it speeds it up however it also leaves the f2p players with nothing or months of endless farming. As the nub sorcerer said (lel) if we implemented the quest idea or something based around that people who don't like to gamble/buy plat may start to realise they are getting somewhere in the game and it can only get better indefinitely if they buy plat, therefore plat purchases will increase, increasing profit for STS and then everyone's happy!!!
