With all due respect, potestas, attitudes like this one:
This game is about wizards not the add ons. If you have a player who wants to play a wolf make sure they understand there taking a secondary support role. Create situation where the secondary support roles shine.
are pretty much the exact problem.
This doesn't really have anything to do with video games. Doesn't even have all that much to do with mechanical balance, except as a proxy. It's simply not acceptable to write off some of the people at the table as secondary support players.
If wizards are mechanically overpowered, that's a manageable issue. If wizards are the True Protagonists, that's a catastrophic issue.
