>>57390774there are always tanks in video games
mobs have to decide whom to attack and that is regulated by aggro
and some classes are better at being able to deal with that
Barbs are melee and have a big hit die, they are tanks because they will be targeted by the proximity-based aggro and they can also take damage without dying
5e has no way for the players to force monsters to attack them so the DM can really target whomever they want but BG3 has no DM, only code
which means aggro exists which means tanks exist
