Additionally, maybe because of the way the game does the camera angle, maybe for other reasons, combat arenas are small in size, and there are no longer any spells which allow the wizard to stay safely out of enemy range. If the wizard is at maximum range to Fire Bolt an enemy, the enemy can move and dash to get within melee range of the wizard, forcing the Wizard to disengage, and even then they'll never be out of range of the enemy.
Dim light disadvantage: Melee gets to counter this with backstab, with a wizard I hope you brought dark vision.
Not that it's a complete fix, but if you have a skull, you can drop it, cast the Light cantrip onto it, and toss the skull to provide light.
