And worth noting that is more costly in tabletop, while, if not playing a module, offers less benefit than the numbers would indicate. The MC requirement of 13 dex (or str) most likely isn't so bad, but it does mean you're 2 levels behind, which means you're behind a full spell level. Second to that, the DM is going likely to tailor the fights to your party's capabilities. So even if you could abuse haste like you can in BG3, the encounter difficulty would increase to compensate (and enemies would use it on you too). The third is that BG3 has set encounters, and there is sufficient xp to be had from those that you can easily over-level the encounters. And you get xp after xp. In tabletop, progress will be much slower, and you're looking at a long, long time to get to the levels we get to here very quickly. And fourth, you can't respec for a pittance, and typically not at all. So if you want those levels of fighter, and you want the con proficiency save bonus, you have to start as fighter, and won't get to do mage stuff until level 3, at which point you'll only have level 1 spells.

So even outside of how the MC works for just your build, just the nature of playing in real life makes MC'ing a lot less appealing.

Also beyond that, a lot of MC'ing also abuses rest mechanics. Just short rest, get your Warlock spells back and smite some more with your paladin/warlock. Well, a short rest is supposed to take an hour. Meaning you can't do that after taking out one room in the Gith creche, for example, because they'll attack you. But in game, it is instant. This even applies to action surge. You can use it and then long rest afterwards. Tabletop, no such guarantee.
