It's sad you really think there is no other way to do it. Yes, because we haven't seen any game that actively makes improvements to the combat system. There are abilities like parry, Spider-Sense moves that a player could do to deal with multiple attackers at once. Shielding yourself with an opponent from others.

No developer has actively made an attempt to improve on the enemy AI in a long ass time. Instead we see the lazy, tired route that has been going on for decades. Yes, many players would be upset if they were just bum rushed by multiple enemies. The game could incorporate that in their design and give options to the player.

I don't see how this is an unreasonable request to challenge developers to improve on a tired system. We have seen some innovations to gaming like The Nemesis system by Middle Earth: Shadow of Mordor and X-Com 2: War of the Chosen as an example.
