It is extremely worrisome if what is translated here is correct. I can 'live with' Larian eliminating racial bonuses being locked to certain attributes, which I think is bad because it has the opposite effect of encouraging diversity. If all races get the same bonuses then what makes them special? I can also 'live with' removing stat requirements for multiclassing, when taking into account the level cap. I also think this is a bad idea but it's tolerable at least.
What is, however, absolutely bad design is to allow for full spell progression by multiclassing. This kills any opportunity cost and will guaranteed pigeonhole every choice into multiclassing. If this is true then there is not a single reason to ever go pure single class. There has to be some rhyme and reason to complexity and accessibility. If you stray too far on the accessibility front you will end up with a shallow combat system that will not keep the player engaged in the long term. What happened to encouraging players to learn a ruleset or system? Why does everything have to be dumbed down in the name of accessibility? So tired of this design philosophy in modern gaming.
