Actually my point was the fact that there is nothing broken about it. You give up a feat to be able to do this, and the impact to gameplay is minor at best.
It would seem to be working as intended.
If you don't like it then don't multiclass. Very easy and simple solution.
And that has proven to be wrong on every point. That you elevate ignorance to virtue is immaterial to the discussion, and frankly not my problem. I would invite you to not "contribute" further.
Proven by whom? Pretty much no one in this thread agrees with you, and even showed that it is allowed in pnp rules.
I and others are allowed to disagree with what you consider to be 'broken' when in fact it is not.
But in any case, the sooner you distance yourself from expecting video games to follow pnp 100% accurately, the easier it will be for you to accept. None of the dnd based video games are 100% accurate to the source material, kind of like the Witcher series on Netflix to the books, expecting this to happen will just continue to further disappoint you.
But technically anything in pnp can also have 'homebrew' rules right? So what does it matter to you if other players chose to make an 11 sorc / 1 wizard and memorize all the spells they want in their single player game?
