Thats why we cannot test casters in game because they real power is show after level 8 if I remember correctly(last time I wasy playing D&D when 3e was out).
You are going to be very sad.
There's been two editions designed to resolve Quadratic Wizard, Linear Fighter.
Caters get more power, but you'll never have your Batman Wizard or CODZilla of 3.x in 5e. The game was specifically designed to prevent you from being the only important character by dint of writing 'cleric' or 'wizard' on your character sheet.
