i think the tier thing is stupid, it's basically saying, you are this good if you have this color which is not usually the case. i understand the qi and being able to kind of 'unlock' the use of new colors, but saying specific colors are for beginners is kinda lame. but that's my only little nitpick, if you lost money it sucks but you invested in it, you don't really deserve a refund. that's like if you bought a turkey for $20 and the next day there is a sale on turkey and it's now $10, you don't get your money back for that.
