Waste of time and breath. It`s easier to ask for a number and an achievement and to verify that than to ask elaborate questions, wait for a reply, and trying to verify that, which is, unfortunately, not something everyone`s capable of as things like these tend to require quite extensive game knowledge. 5 hours of lfm for a pug is unacceptable, and that`s exactly what you`re looking at if you try to ask everyone questions like those.
You ask them for a guild application, not for a goddamn pug raid.
