Best of luck. Any time you touch the overwhelming power and versatility of Wizards, you get vocal, nasty condemnation.
I would not play a game that "rebalanced" Wizards. I wouldn't be "nasty" about it, but I certainly would not play that version or buy any products when 5E is around, available and widely supported by 3rd party creators. I would argue it is not just "Wizards" though it is spell casters and the entire spell casting mechanic as defined in 5E. Even martials like Paladins and Rangers and several subclasses of Monks, Rogues and Fighters rely heavily on magic.
I have been playing since the very early days of 1E AD&D and 5E is my favorite rule set by far and for mulitple reasons. Bounded accuracy is one of those reasons, and the way they highlighted spells and casters is another. In terms of fun for most players I think was a major improvement.
