You're not even any good at what your bloated ego tells you you're good at. But feel free to keep belittling yourself.

Hey ! . . . the penny has just dropped ! . . . a female forum camper ? . . . or one of the limp-wristed brigade ?
Other than that you really shouldn't take yourself so seriously.
All of this self-protection/defensiveness is born out of fear.
Take the bung out of your arse and chill.

Just as Hickory said; though, you will have whatever Witcher gear you've crafted carry over to NG+. What you will have to do is find the "Legendary" Witcher sets, if you're inclined. So, if you have a Grandmaster set of Ursine gear (if you have Blood & Wine, otherwise it'll be Master-crated) for example, this will see you well into Velen before you really need any different armor, especailly depending on which skills you've invested in, runes that are active and glyphs, etc..

Before starting a new game plus.

Make sure to make all potions, armors, and weapons. Because all the recipes will be removed.
