Ok, Supesucks...maybe I'm not getting my point across (visually/vividly)
Try to picture this: WW (98-100 ton strength level I believe) twirling her lasso up in the air around her head like she's going in for a calf riding a horse at the rodeo. Now....take WW off the horse, and put Rogue's neck in the rope. Rogue may be strong, but she is not winning any strength feats against Diana anytime soon. Once the rope is on, good-night, I think. I could be wrong.
Can't you picture WW with Rogue's neck in the rope twirling her at superspeeds and smashing her up against mountains, building, cars, trees, etc.?
The lasso Wonder Woman has is the Lasso of Truth that was mainly to "open the eyes" of her opponents to have them see the errors of their ways. I suppose she could try stangulation, but that might be hard to do with Rogue. Rogue is also not heavier because of her durability; she is still human in basic terms and doesn't change in scale as gods like Asgardians and Olympians do (i.e. Enchantress is about 600+ lbs?).
On Rogue's absorbtion, she also has some trouble when her opponent has a stronger resistence that allows them to react (i.e. Impossible Man, Wolverine), or their power either cancels her's out (i.e. Scrambler, Leech) or is too much for her (i.e. Death's Head).
I do not know how Wonder Woman was made so powerful here to be a competition with Superman. Unless my material is extremely dated and she has morphed to a frightfully more powerful character in the past few years, Rogue could take her. People discredit the fight between Wonder Woman and Storm, but I still see Storm winning in that fight.
