The DKS attribute system was the perfect example of how each individual attribute point did almost nothing, but when you pile up several dozen, suddenly all those little fractions of a percent of restoration per second add up to a pretty hefty percentage.
This made a high-INT character have essentially infinite mana, and a high-STR character regenerate quite a bit of health per second. Larian tried to compensate for that by giving the enemies high burst damage, and that was somewhat effective, although it did require turning the difficulty up to Nightmare.
