Why?
Cantrips are very weak when compared to other at will attacks. High level spells are limited to 1 slot a day. Cantrips are limited to a finate number known. There are too many spells that require concentration. You HAVE to pick a flavor of wizard. Fighters have more stat increases. All this stuff was done for game balance when other classes got huge increases in power well beyond what spellcasters were nerfed to.
