Having played with a 2 wizard multiclass for a bit in Act 3 now, I no longer care at all if Larian remove the ability to memorize / retain higher level scrolled spells on multiclassed Wizards.
Its an OK build, definitely a lot better than a pure wizard, yet completely mediocre and sub par to a pure sorcerer. Personally my gameplay wouldn't be affected as I will never play a Wizard in this game in its current format nor use one in my party so long as a pure class Wizard remains as gimpy as it currently is.
As for the term 'exploit', I would personally consider an exploit to be something that 'breaks' the game in someway. If a multiclassed wizard is somehow an exploit, than a level 12 sorc must be a mega exploit, even without the restoration point 'actual exploit' being abused.
