thor,silversurfer vs thanos with a GL ring(no weakness)

I cant stand how the GL ring was meant to be one of the most powerful weapons in the DCU, but the original one had a weakness to WOOD, and the others (except kyles) have had a weakness to YELLOW!!!

It's like, "i've got the most powerful weapon ever created, with a power source as old as the universe itself, but I cant knock down a wooden treehouse, and I cant beat you if you wear yellow clothes."

Yellow? Ahahahahaha. That's classic. So basically Green Lantern is powerless next to the song 'Tie A Yellow Ribbon 'Round the Old Oak Tree.'

but kyles ring has no weakness

I think it seriously is a problem of DC that they make there Heroes pretty much invincible but they still lose against some idiots (for example Kyle he got this undeefeatable power ring and still loses every other day, or Flash c'mon he can run at the speed of löight, do you know how ****ing fast that is and people like Dr. Alchemy or Boomerang are still a problem for him)

The funny thing is that with Batman it is the other way around from his powers he shouldn't be that strong but he still kicks everyones ass if he wants to.
