I agree with everyone who has said that concentration is fine in principle, but poorly implemented in BG3 in practice. I really hope addressing the unnecessary number of factors that prematurely break concentration will be addressed as part of tuning and tweaking over the next eight months.
It’s true that even with an excellently realised concentration mechanic, the fact that each character can only maintain one concentration spell at a time is going to mean that there are certain spells that are unlikely to ever be selected by gamers whose priority is to optimise combat effectiveness every playthrough. But I don’t really see that as a problem. There are still plenty of cool spells for those players to use, and personally I quite like picking some of the more situational, weird or just weak spells that might fit the RP for my current character and trying to make them work.
