The issue is that while these spells theoretically exist for a wizard, they can't know all of them at that level without DM fiat.Social:
Friends, Comprehend Languages, Disguise Self, Distort Value, Silent Image, Alter Self, Detect Thoughts, Enhance Ability, Pyrotechnics, Skywrite, Clairvoyance, Major Image, Sending, Speak with Dead, Tongues, Charm Monster, Divination, Polymorph
Alarm, Floating Disc, Alter Self, Augury, Darkvision, Enhance Ability, Flock of Familiars, Find Familiar, Invisibility, Levitate, Magic Mouth, Misty Step, Spider Climb, Feign Death, Gaseous form, Major Image, Nondetection, Sending, Arcane Eye, Flying, Dimension Door, Divination, Greater Invisibility, Locate Creature, Polymorph
If you think a handful of superiority die to some persuasion or investigation checks (particularly when those stats are necessarily low for fighters unless we can assume everyone has a 20 for whatever stat they wish) can best options like that, I no longer suspect you are making any attempt to argue in good faith.
Or that you do not understand the system - you get to decide which is more charitable.
Which ones would you choose out of this list? Why would you believe they cause a domination of the two noncombat pillars?
