I realize the new store interface is great for beginners who are still learning the game, but I like the old one a lot better. New one has caused me to spent plat unknowingly, and it just takes a lot longer. With the old interface, when I was fighting overlord and my tank potion ran out, I could quickly buy a new one and get back to playing without be killed. With new interface, It just takes too long to do this. :/
I know everyone will probably get used to it over time but I'd still like to see an option that's lets you switch between them, because the old one was better IMO.
