11th level Wizard gets 4/3/3/3/2/1
11th level Cleric gets 4/3/3/3/2/1
11th level (Wizeric) gets... 4/3/3/3/2/1

Eh, I think it's probably worth losing a single ASI in exchange for 3rd level spells.
Either 4 classes at 5 levels each, OR 3 classes at 5 levels, one at 4, and a single dip in a fifth for the cantrips.
For the 4 class option, Bard/Cle/Dru/Wiz skip Sorcerer because too much overlap with the Wizard list.
