We must assume that Rand will need all the lands behind him to beat the DO at Tarmon'gaidon. Lews Therin must have had all the lands behind him in the war of power. Rands hardly thought about shara. The aiel say that theres dragonsworn fighting in shara so if Rand and some Asha'man skimmed over there and told who they were and proved it with a bit of channeling they could take the dragonsworn back to randland and he has more men. Who knows. There could be more dragonsworn for Rand to pick up in Shara depending on how big it is then all the troops he currently has. Thoughts anyone?
