Playing a Cleric I feel like a bit too many spells require Concentration. But it's a great mechanic that fixes the ridiculous buff stacking of previous editions. Perhaps the next edition could just remove a spell or two from the Concentration list. I like the idea of "choose your buff" and it being powerful. There could also be a Feat that would allow Concentrating on a second spell.
BG3 needs to stop the unavoidable AoE fire spam from low level enemies though. And falling Prone should NOT be an automatic loss of Concentration. Concentration is a nightmare in BG3 and you tend to lose it very quickly always.
