Okay, be quiet with the bird thing. It shows that orbalisks have a degree of resistance to physical attacks, just like any crustacean, not that it is harder than durasteel or mandalorian armor or anything of the sort (and certainly not diamonds). Got it?
Example: You're wearing a lightly padded electricity resistant suit, and you fall in a tank with an electric eel. The suit saves you from the electricity, and you climb out of the tank unharmed. Your friend then runs over to you, sees that you're okay, and pats you on the back. His patting you on the back didn't phase you much, due to the light padding and the weakness of the hit, so does that mean that the suit is just as efficient against physical damage as it is against electricity? No, not by a long shot. The degree of danger between the electricity (the lightsaber), and the patting (the birds claws) are not even comparable.
Now, there is also the fact that lightsabers have (for whatever reason) transfered kinetic energy, meaning, they hit you with physical force too, depending on how hard you swing, along with their damage from energy.
Now, take the eel example, and have it swim into you as it shocks you. The physical damage is there, it is just easily negatable thanks to the light padding (the physical damage a lightsaber does can be blocked by orbalisks because they are hard, and lightsabers aren't typically swung with enough strength to do more than just distribute the physical force over the body, and you just feet a sleight impact).
Now, this is what it's like against Mace Windu:
You go back to the aquarium or wherever it is that you and your friend get dressed up and play with eels. The same thing happens, and you fall in the tank. You see the eel, but, this is a new eel. It is 25 feet long and a very fast swimmer. It bolts at you, lightning fast, and unleashes its electricity. Thanks to your suit, you're fine, but, this one also rams into you... fast and hard with a lot of force (to account for Mace's Durasteel-wrecking, diamond-shattering strength) in the crotch (to replicate a shatterpoint on a smaller scale), and you're down for the count. The electricity did no damage, but, the physical force had you throwing up and then blacking out.
So while the padded suit (Bane's armor) will protect you against all sorts of electricity (lightsaber energy), and against pats on the shoulder (an average lightsaber hit), you will be royally dicked when a huge eel comes at your crotch with pelvis shattering speed.
There is also the fact that Orbalisks have never been tested against repeated lightsaber attacks, and other substances that have been described as lightsaber resistant ended up not staying that way, like cortosis and mandalorian iron (your suit might nobe so effective if the eel shoots out a few charges of electricity).
Need anything cleared up? If you do, I'll try again.
