As I have already noted - the physics (and therefore the math) of dropping a rock from orbit is not likely to bear much if any resemblance to that of travelling at FTL speeds.
I'm not arguing that point at all.
I am saying that he also travels through space at speeds infinitely slower than c. But I also get that your true point is this:
Under the influence of the ring, moving himself with loads of fine control and correction, will also bear little resemblance to dropping a rock in freefall from orbit and hitting a smallish target. And, if he carries the rock down, under power, he's losing the assist of gravity
My response is that Hal Jordan, human experimental jet test pilot- is unlikely to have any concept of the (DC universe) physics involved in doing many of the things he does- FTL, generating infinitely malleable force fields, travel via wormholes, generating his uniform ex nihilo. The Oans did all that math and built it into the rings. All the operator has to do is conceive of the doing ad will it to be so. Essentially, the Oan rings are as close to rings of infinite wishes as exist in the DC Universe.
If Hal can conceive of dropping a 1 ton asteroid from the belt between Mars and Jupiter on the corner of 4th & Main of Star City- a relatively stationary target as opposed to a person in motion on said street- he doesn't need to do the math, the ring will do it for him.
They DO have limitations- mainly, the minds of the wielders. Once, Hal had to give a ring to a being chosen to be a GL, but the being was blind. As in, the being's species was blind. Without a concept of light and sight, Hal couldn't teach it the oath required to recharge the ring. Even the ring's ability to act as a universal translator was ineffective, since there was no words related to "light" in the being's vocabulary. He had to formulate in his mind an oath that kept the spirit of the original but operated on concepts the being could comprehend. (He succeeded.)
he might as well just pick up a car on the surface and whollop someone with it at that point. Far simpler.
Except, as we all know, that would be 100% ineffective on any of the targets he'd consider dropping an asteroid on- they're all too tough and strong.
As I said - one GL *allowed himself to get run over by a mundane truck and die*. The ring doesn't make you a genius, or even particularly observant. It is a dangerous weapon, but the wearers are just people.
But, you know, if your'e not going to allow for plausible limitations on them, fine. The DC heroes win. End of debate. Happy?
Part of discussion is "give ant take" guys. You're not allowing for any. Makes it kind of pointless.
Umbran, I didn't write up the powers and limitations of the characters in question, reasonable or otherwise, which is one reason why I said in my initial response was that who wins depends on which versions of the characters and which team lineups you look at.
I'm perfectly willing to discuss the abilities and flaws of any of the characters in question, at any time in any character's multiply retconned origins and official stats.
Sure, the Avengers have some nifty tricks up their sleeves, too. Thor can open up trans-dimensional portals. But it takes time for him to do so, and he can't do much else while doing so.
Cap's shield is so good at absorbing kinetic energy, he has withstood blows from some of the biggest powerhouses in the Marvel Universe- Hulk, the Thing, Thor, Iron Man, etc.- and lived to lecture them about their tempers.
Scarlet Witch is potentially as powerful as Dr. Strange near his peak. But whether her hex powers can merely cause malfunctions or full on alter reality depends, in part, on her sanity at the time.
The problem is simple: Marvel characters- even those directly based on DC characters like those in the Squadron Sinister/Supreme- tend to be written as being significantly less über than DC characters. That's has been one of their draws. Even the most powerful Marvel superheroes tend to be more human...and more limited for it.
The reason why I hated the Cat & Truck storylines- or similarly, Batman's punching Guy out- so much is not that the GLs in question had their mortality revealed- that is a granted. What I objected to is that both Guy and C'hp were experienced Green Lanterns, and the events in question were so predictable & preventable that a GL getting hurt or killed in those ways would have meant they shouldn't have survived to become experienced Green Lanterns in the first place. Neither attack should have gotten past the auto shields that 99.99% of all Lanterns use for personal defense.
At the very least, Guy- who we know had used such a force field in the past- should have been protected from those attacks. In his case, at least, it wasn't a case of his human limitations, it was writers tossing out a character's standard operating procedure for comedic effect.
