the problem with dungeoneering shields is that they only soak damage that hits over 200. bandos' max with ranged is low 300s, so it's only going to activate like 40% of the time, and only going to activate about 5% of the time for the range minions. also you get no reduction against the mage, who actually does like 25-30% of the damage you receive. 40% activation x 20% reduction = 8% reduction of graardor's damage 5% activation x 20% reduction = 1% reduction of ranger's damage vs: 100% activation x 30% reduction = 30% reduction of graardor's, ranger's, and mage's damage the +32 ranged defence helps, yes, and the +2 stab helps, yes; however, the benefits of those small bonuses (yes 30 ranged is small - your ranged defence is 303 with divine) pale in comparison to being able to absorb about 4x more damage.
