Some people putting the cart before the horse here.
Concentration is fine the way it is. Prohibiting a caster from stacking buffs on top of each other is by design and a healthy thing for the game balance. No pre-cast orgies, no CoDzilla, no overpowered CC, less caster-martial imbalance.
The actual issue for tabletop is that some spells shouldn't require concentration. And for BG3, that there is too many instances of unavoidable damage at low levels, too many enemies with ranged weapons, enemies having additional attacks or instances of damage they shouldn't, and the prone condition causing concentration to be broken.
It's just one of many instances that shows that Larian either does not appreciate the extent to which their homebrew impacts the base system or that they were willing to experiment by throwing stuff at a wall and see what sticks during EA.
Exactly this. The spiraling set of consequences which makes it a worse game resulting from Larian's homebrew is staggering to behold. I hope they rethink it.
I am aware that novels are not a foundation for game design. But they tend to give an insight as how the world we are playing in usally is thought to be.
No. Go read any licensed novel for any given franchise based on a game or videogame: the authors tend to show a gross ignorance of the source material and either retcon or outright ignore important facets of the game world in order to force their often ill-thought out plots. The Halo novels come to mind as an especially egregious example, but many of the books written in the various D&D settings suffer from this as well. The exception, of course, are the early Dragonlance books: legend has it that those were written to describe the actual campaign the authors played in.
Either way, the books you are describing were written in the TSR days. Wizards of the Coast famously surveyed their players to find what they liked and didn't like and balance turned out to be a highly desired feature. After years of fumbling around, they eventually arrived at the massive success story that is 5E D&D: the franchise was basically dying prior to that. The resurgence in interest in Dungeons and Dragons is primarily due to 5E's design decisions: I would say balance is a key feature of that.
