Infusion only really works well if you also use an enchantment on top of it. When I used to use Ruler's Sword and enchant it with Sunlight Blade, the damage increase was barely noticable. But when I wielded Defender's Greatsword and used it's own Lightning Enchantment on it on top of Lightning Infusion, the damage is vastly greater. This is because enchantments not only add a flat bonus damage to the weapon, but also increase the total Magic/Fire/Lightning/Dark damage of the weapon by 30%.
