What, you can't see difference between BG1 (walk out of the city, engage wolf, get crit for 10 hp, your fighter has 10 hp, rekked lol), and this - get out of caravan, left click 2 wolves (that are more of a size of a horse), kill 2 bandits (including an archer who just shot arrow after arrow into the backside of 1st level char - "glance! 0.5 hp damage"), kill more bandits, kill whole enemy party 3 on 3, kill oozes, more oozes, kill giant spiders...
All with suboptimal party of 2, then 3 characters - hurrah for regenerating

In IE trying to kill a bunch of enemies like that straight on with just 2-3 characters is death sentence, you had to use entangle/sleep/heal/bows/pots/oil of speed... use something.
Here NPC fighter just tanked everything that's all. "yeah you can get knocked down (fighter loses 5% hp), you can get badly beaten (fighter loses 10% hp)".
