The nerfed CC comes fron D&D and is not a invention of Larian
That's just an ignorant statement. A lot of durations have been reduced to unusable levels. The constant spam of surfaces and elemental damage from weapons make you roll for concentration non-stop. Falling prone ends concentration spells immediately with no save. Playing a concentration caster just isn't any fun in BG3.
On the other hand, you can haste yourself to cast two Fireballs, or three Fireballs with Quicken Spell.
There is some "only active offensive skills are fun" philosophy at Larian they just can't get over. And they have basically ruined the fun aspect of D&D combat for a lot of players, shamelessly promoting their "fun OP damage dealing" way of playing. This is also why something as simple as the Dodge action or Ready action were never implemented. They are passive and don't do something flashy and amazing.
