I never bashed anyone. All I said was that learning how to use a scraper would save you time. Funny that you went through my gallery to point out your perceived mistakes in my cakes. I never claimed they were perfect and I disagree with your opinion that my buttercream looks unfinished. Why, because there might be a few pock marks or spatula marks? It's BUTTERCREAM. If you want perfect flawless finish, use fondant. The majority of my cakes are gratis and I'm not going to sit there smothering my buttercream with non-food safe materials for two hours to give the illusion that it's fondant when it isn't. I would rather spend that time hand-cutting fondant decorations or not doing cakes at all. If you get paid to do that, more power to you.
The recipe I use for most of my cakes barely crusts, and those methods wouldn't work for me if I wanted them to. Consequently, I use a scraper.
