I would like it as well if they stick to the DnD 5e rules, giving Goblins high AC and low HP. High AC low HP enemies are simply not meant to be attacked by weapons. Use Spells or skills that target attribute saves. Or inflict status effects on them (e.g. prone, sleep). Or use AoE spells and skils to increase your chance of hitting. But giving them low AC and high HP just to make the standard 2H melee Fighter more viable in every situation sounds kind of dull to me.
