Rand should be somewhat above baseline too: when focused he resisted the assault the Dark One (a fellow 2-A) with ridiculous easy.
The Dark One attacked him. It came like a storm. A burst of wind so terrible, it threatened to rip Rand's skin from his bones. He stood tall, eyes toward the nothing, crossing his arms behind his back.
[...]
Rand stood before the blowing winds, stood strong, though his eyes watered as he stared into the darkness. How long had he been in this place? A thousand years? Ten thousand?
[...]
Rand stared at the Pattern, resisting the Dark Ones attack. He did not move or breathe. Breath wasn't needed here.
[...]
The Dark One chose then to attack him in force. The pressure came again, striving to crush Rand into nothing. He couldn't move. Every bit of his essence, his determination and his strength focused on keeping the Dark One from ripping him apart. [...] He opened his eyes and placed his hand before him, palm against blackness that felt solid. His self that had fuzzed, becoming indistinct as the Dark One ripped at it, pulled together. He placed his other arm down, then heaved himself to his knees.
And then, Rand al'Thor—the Dragon Reborn—stood up once again to face the Shadow.
[...]
The Dark One still strove to destroy him. Rand felt strong despite the attacks. Relaxed, complete. With his burdens gone, he could fight again. He held himself together. It was difficult, but he was victorious.
Rand stepped forward.
The Darkness shuddered. It quivered, vibrated, as if disbelieving.
[...]
The vast Shadow thundered and shook. It sent jolts through and across the world. The ground rent, the laws of nature fractured. Swords turned against their owners, food spoiled, rock turned to mud.
It came upon Rand again, the force of nothingness itself trying to pull him apart. The strength of the attack did not lessen. And yet, suddenly, it felt like an idle buzzing. [...] The Dark One's attacks lost meaning. If they could not make him yield, if they could not make him relent, then what were they?
Possibly Rand atteined some kind of Abstract Essence at the Last Battle, presenting himself as the polar opposite of the Dark One.
OH, I DO, SHAITAN, Rand said softly. I EMBRACE IT, FOR DEATH IS—AND ALWAYS HAS BEEN—LIGHTER THAN A FEATHER. DEATH ARRIVES IN A HEARTBEAT, NO MORE TANGIBLE THAN A FLICKER OF LIGHT. IT HAS NO WEIGHT, NO SUBSTANCE... Rand strode forward, speaking louder. DEATH CANNOT KEEP ME AT BAY, AND IT CANNOT RULE ME. IT COMES DOWN TO THIS, FATHER OF LIES. WHEN HAVE YOU INSPIRED A PERSON TO GIVE THEIR LIFE FOR YOU? NOT FOR THE PROMISES YOU GIVE, NOT FOR THE RICHES THEY SEEK OR THE POSITIONS THEY WOULD HOLD, BUT FOR YOU. HAS IT EVER HAPPENED?
Not only Rand endured everything another 2-A trown at him, but he also Power Absorbed and totally overpowered the Dark One (I will CRT the Power Absorption thing).
Rand punched through the blackness there and created a conduit of light and darkness, turning the Dark Ones own essence upon him. Rand felt the Dark One beyond, his immensity. Space, size, time . . . Rand understood how these things could be irrelevant now.
With a bellow—three Powers coursing through him, blood streaming down his side—the Dragon Reborn raised a hand of power and seized the Dark One through the Bore, like a man reaching through water to grab the prize at the rivers bottom.
The Dark One tried to pull back, but Rands claw was gloved by the True Power. The enemy could not taint saidin again. The Dark One tried to withdraw the True Power from Moridin, but the conduit flowed too freely, too powerfully to shut off now. Even for Shai'tan himself.
[...]
The seals crumbled. The Dark One burst free.
Rand held the Dark One tightly.
Filled with the Power, standing in a column of light, Rand pulled the Dark One into the Pattern. Only here was there time. Only here could the Shadow itself be killed.
The force in his hand, which was at once vast and yet tiny, trembled. Its screams were the sounds of planets grinding together. A pitiful object. Suddenly, Rand felt as if he were holding not one of the primal forces of existence, but a squirming thing from the mud of the sheep pens.
Finally Rand may be able to counter Vecna's precog by testing the Pattern. Still, it is unknown how much power Rand could have mustered without two female channelers assisting him with Callador, so if they are not present against Vecna, and Rand doesn't have the Choden Kal to cope the loss, Rand would be significantly weaker. I'd give it to the maimed god, because everything Rand can do, Vecna can just do better.
