The ironic thing is that this blockade does not really exist, Xandra told her that she was not broken, that she had to learn to control it, and then when they joined their powers, Rogue's powers increased (even more) and evolved) so her powers have not really stopped growing and progressing since she gained control, only that in some way now he does not know how to control them.
Now he must learn to control more than one thing, the turning on and off of his touch, and all the things she had acquired and learned in XMLegacy, and her new powers of distance attack by draining by an aura of energy.

I love you Kelly, you are giving the original powers of Rogue the development they deserve, and that they had not since Gage (and hawksbill) wrote it in Legacy.
Because after them, they only remembered the flying brick, something that had me very annoying to tell the truth, I love those powers, but the writers must remember all the powers of Rogue, not only the generic ones, that ironically what makes Rogue oneThe most powerful beings are the powers of absorption, not the generic powers of superman XD.

Kelly develops it as a character, and as powers must have everyone happy, since it gives good to all its generic powers and its powers of absorption, and I like that.

The loss of control was not to absorb Simon WM, she had already absorbed his powers before, so it was not for him, the trauma appeared because she literally absorbed hundreds of powerset, she on panel and off panel absorbed almost all heroes who were in the teirra, and turned all that energy into super strength, making it physically stronger among the heroes, and by far, only among the avengers and xmen, there were several class 100, and Rogue we know that she adds the forces of the persoanjes that absorbs, and those not super strong, in that number turned their energy into brute force, normal that some trauma caused and damaged the advantage that Xavier gave her to acquire control, that is why she wants to discover for herself control it.
