I think duelist used skill Parry. Not Attribute Int. Talking about 2.5 rules.
Also there is an Epic feat for soak dmg. Like absorb 1dmg from every hit.
Also there are Natural AC which stack and Deflection AC bonus which doesn't.

So options how to make a build a character or how to take down an opponent is more.
Say that there is one dodge number which is the only source is kind a plain.

Anyway, AD&D managed to introduce weapon combat, parry, backstab, AOE skills, AOE spells, cc, even AOE cc all in one package but avoid overwhelming overload like DOS.
