Don't go hating on each other, there's more than few people here doing great work and they deserve as much credits as they want.
IMO business is business if Wratah can get clients with his signatures costing 70+ then he's allowed to do so. What is unfair is people thinking that the work of others is worthless. Exile, Wratah, Mike, Schlurbz and anyone else doing sigs for money shouldn't jump into each other's business. It leaves bad taste in everyone's mouth.
Wratah did a great job for the kishiro, sadly it didn't stick but I found his sigs to be different from other designers here because I wanted motion. and from what I understood he killed himself doing that job cause it was pain.
At that moment only Ophidian offered to make a logo, and he got 100mil for his (actually Order did because he quit)
When a Corporation is paying a logo, it should cost tons of cash if it's good. Especially if it offers links.
Individual players? That depend on how much are you fond of him.
