Lots of people here think OL should work harder to overcome all the scry wards, or prevent people like Lex Luther from flooding the world with them. If I was in OL's situation, I would purposefully support and assist all my enemies in creating more scry wards, and I would do so for the exact same reason that I support end-to-end internet encryption; because I think privacy is a fundamental human right, and that the world is a better place when law enforcement types, even well meaning ones, are unable to gather information without a warrant. And that's not even getting into how this protects the Earth from extra-dimensional threats and hostile enemy lanterns.
I see this as a net win for OL.
I'm not sure the analogy fully applies though. Scry wards are good at blocking magical scrying and the song's standard scan. If a Lantern wants some information and doesn't care about being detected getting that information, scry wards do jack shit. It inconveniences them, but that's all.
For magical espionage, I agree, scry wards should be implemented wherever avilable, as mages are more common on Earth than Lanterns. Although I do wonder if a mage would be able to make sense of a hard drive's data even ignoring warding.
There are currently only two Lanterns in the galaxy who could be considered hostile to Earth, and if Larfleeze is coming then protecting your financial records is the least of your worries.
OL made that shield bracer thing for Kaldur when he was considering wearing ocean master's armor.
It still required magical energy.
Where are you getting the "They can be powered by earth's magical field" thing?
Paulphidian warded the mountain by forming scry runes in the walls. No mage required.
On the contrary. The SI explicitly can create construct runes. It came up after the Reds attacked the mountain. The thing is, by themselves they don't do very much. The amount of local magic they shape on their own is tiny. What they're mostly used for is a) making it easier of a mage to cast a related spell and b) bind a spell to an object and keep it running.
Actually, that makes a lot of sense. You could sum up magical runes as "Shape any ambient mana, including Earth's diffuse arcane field." Mages then are just very concentrated sources of mana.
The Guardian's anti-magic approach is overwhelming firepower, backed by direct Guardian support of necessary. Someone would have to be twisting the universe into a pretzel before it came to that.
... Yeah, I guess that does work. When you have the option of overwhelming firepower, it's not worth your time to develop specific countermeasures against such a rare phenomenon.
In other words, a more accurate ring slogan would be 'Power Rings Are Actually Finicky & Specialized, And They Kind Of Shit The Bed When Actually Competent People Decide To Oppose Them.'
Hardly. Scarab warriors would struggle to beat an individual Lantern, and Scarabs are just about the best human-portable general purpose weapons in the galaxy. One of a ring's basic functions is easily countered by magic, but magic is generally pretty potent.
Hell, back at Belle Reve, a guy with the superpower of ~TWIRLING~ was able to fuck up the ring for an appreciable length of time. When the human version of Top Man can inconvenience an experienced ring-slinger, "awesome" no longer becomes an accurate total summation of their capacities.
I just read that fight scene again. The first two attacks didn't work, but that's it. He got through a cage of filaments, which are explicitly not as strong as thicker tethers, and gas didn't work. Donna then broke his hip and OL shocked him and shock crowned him. He mildly incovenienced OL for a few subjective seconds, thats all. When OL was simultaneously defending every hostage in the room, and taking out most of the Kobra cultists, being slightly delayed by a guy with really weird powers is hardly a black mark on his record.
