I don't understand that claim at all. First of all what it does it change him from being soft-banned on the development server and potentially actually really banned later, to a reasonable power level. See Chump, Sotek, BT's comments that Lum was winning a hell of a lot versus the field, far more than his share and dominating in a bad way. Next, what do you mean he is mono-purple? So if you could buy gem essence, you won't? If you could buy knockdown, you won't? If others are buying attacks and you could buy Self-Improvement, you won't? If you could buy a roundhouse, you won't? These would indicate playing poorly. Also, if in all those cases you would not buy any non-purples, I don't know why you'd buy them with any other character either. In short, it's just too dangerous to spend tens of thousands of dollars to ship the game when one character is so big of a problem as to possibly be banned, and second, I don't get the purple comment at all.
