THAT is why you have other members in a party. It's TEAM-based.
Now, now ... i never said that is single character, that is once again your own interpretation. :P
Yes, come on now GM4Him. The actual combat cycle for a party in BG3 is:
Fighter attacks and drinks a potion
Enemy attacks the fighter
Druid throws a potion at the fighter then attempts to shove an enemy away from them
Barbarian automatically throws an enemy into another enemy
Cleric throws a potion at the fighter then attempts to shove an enemy off a cliff
Repeat
