Can't seem to reply to your most recent post, so I'll do it here. The regret towards killing Lassara doesn't change the fact that she forgot to clean up the mess she created, as Shadow Wars showed Niadra thought Kerrigan's last order was to kill the Protoss people. As for interacting with the Protoss, she made it seem like just because she changed her mind towards them, they'd do the same. This was shown at Ulnar when she met up with Artanis. You can argue similarly in the LotV prologue with Zeratul, and that she didn't listen to what he was trying to tell her. To me, it seemed like her mentality was that she was the only SMART one who actually knew what to do, whereas all the Protoss were too damn stupid to do anything except play into Amon's hands (now granted this did somewhat happen, but still)

I still felt it was the lack of strength in NCO. As shown in Evolution, the Dominion isn't in a strong position and all that. You can argue the zerg were weaker as Zagara took over the swarm and remained silent, but it was never explained how much feral zerg were still out there, but it's more than enough to bring catastrophe to the Dominion.
