The rebellion was not necessarily required for this.

You have it backwards. The only hope for the Tower was a pro-Rand Amyrlin. Lelaine or her ilk could not have fixed things without going over to the pro-Rand side. The Tower broke because it was too dominant and obstructive to Rand. Rand has plenty of Aes Sedai, most of whom were loyal to the unbroken Tower, to do whatever he needs Aes Sedai for.

And given that Egwene plans to punish Rand for the bonding of Elaida's expedition to the Black Tower, despite knowing the circumstances and the facts, how can you assert that her reign is good for Rand?

Prove this absurd statement. The Seanchan launched a relatively small raid. Without the rebellion, perhaps the Tower would have been better situated to fight off the raid, and in any case, the Ajah heads and most of the Hall survived, only one through Egwene's intervention. They were functioning just fine and would have got over their weepy-time afterwards, Egwene or no.

Absurd exaggeration. They were only trying to hurt the Tower. Destroying it was neither their expectation or aim. If they thought their raid was going to destroy the White Tower, why send the Bloodknives? Plainly they expected the Tower to survive their attack, otherwise the Bloodknives would have no one to attack.

....and? This might suck for the Aes Sedai, but since their function has mainly been to obstruct the development of the world, no big loss in the grand scheme of things.

Assuming she would be inclined to either take Nynaeve's advice or approach Rand sympathetically instead of punishing him to uphold the exalted status of her followers. Why don't you show where she has EVER taken Rand's advice? And how is her being in a cell where she did have some room to move a superior empathetic experience to Elayne's having been in an ACTUAL box, like Rand?

Bull on both counts. Elayne's biggest remaining threat comes from an Aes Sedai. Without the Tower, Duhara's interference is nil. Elayne's claim to power is due to her ancestry. Since people have been talking about her being the first queen who can admit she is an Aes Sedai, the Tower is more of a liability to her than the reverse. That is why the Tower is so interested in seeing her on the throne - they want the prestige of an Aes Sedai queen. That would not mean anything to them if her rule and power came entirely through them. And let us not forget that it was the machinations of the Tower that incited the other claimants to try setting themselves up when Rand disappeared.

Which has nothing to do with Egwene or the rebellion. ANYONE could have done what she did with the information Verin gave.

Why don't YOU go to a site where that smiley works? Whether or not the rebels are important might be an issue, but your assertions largely fail to prove their case.
