Time travel will not help them in this current timeline, where the events they lived through have been lived through. They happened. We cannot make them un-happen to this timeline's Ancients.

The only thing we could achieve is creating a second copy of those people who might have a happier life than the ones we know. And as I said above, whether you want it or not, the basic character of the WoL as written by the devs has gone to the past to observe what happened and come back to their present day to apply that knowledge.
