Yes You Are Right!

But Any New User Will Not Like To Go Through Such A Long Process If HE/SHE is feeling helpless.

Again this is Modified for new users..

Giving them exactly what they want is top most priority.

To say that this is for bricked phones is inaccurate. These are the steps to follow when you want to flash any ROM, for whatever reason,even if your phone is working flawlessly.
