Going for a successful run!

Good afternoon. I have a suggestion to improve the gameplay and keep new players in the game. I have been an active player since the beginning of the first season, and it was time to gather enough information. Why do most players leave? Mainly because they don't have the ability to make a playable item build on the hero. Why is that? 1) Pricing at auction. The player knocks out the first flame, goes to the auction, sees prices for the things he needs in a couple of hundred or even thousands of this flame, and soon quits playing. 2) Most of the legendary things - useless and unnecessary garbage, which cannot be “attached” to the build and, accordingly, cannot be sold.3) crafting is not clear to beginners
