Why wouldn't this turn into wraith vs ancients round 2? Ori have superior technology. Once wraith get their hands on a power source they begin overwhelming the Ori with numbers. Ori win every battle but wraith keep coming and it becomes a battle of attrition.

No. The Ori Ships have the Priors.

But why would that affect the outcome? We've seen that the ships can be destroyed if they take enough damage. What qualifies as enough is absurd but this was true back during the Ancients too.

The Ancients were intelligent people, but at the basic level, they have no clue.

For the cry out loud, the Asgard did ask the Tau'ri for help with the Replicators.

Because as Thor said, they need less intelligent solutions to stop the Replicators.

Look at this scene. If the Wraith did attack the Ori. https://www.youtube.com/watch?v=UNeS7qMMvbw

That battle doesn't really say that it would turn out different for the ori than it did for the ancients. The exact same thing happened with the wraith when they fought the ancients. They fight, the wraith get slaughtered. So the wraith send more ships to get slaughtered again. And again. And again. Multiply that a couple hundred times, the total tax on the Ancient shields means the ships have to retreat back a bit to the next territory. Rinse and repeat ad infinitum until the wraith have consumed all the territory.

Also, the replicators don't really mean much. The asgard's mistake was to think their technology could overcome the enemy, a mistake you see when you see other ppl make when they talk about replicators against other universes.

Well, the Prior have powers and they could do to Wraiths that attacked them with they did to Volnek.

If the Wraith send 40 Ships, they will have to destroy the ships if the ships were to return.

The Ori will use the Trojan Horse Approach.

But would that really be able to turn the tide against the wraith? I mean if they could, why didn't they use an army of indestructible zombie people against the milky way instead of sacrificing their own followers? The zombie thing seems to be effective against a small group caught unaware but there seems to be limitations to using that else they'd have an easy unkillable army.

The Ori don't care of their followers. They are nothing, just pawns.

They're also a mean of getting power by siphoning off of them through worship. Sure subjugating the Milky Way would get them more in the long run but they'll get even more if they don't toss them away.

There is one thing, I don't understand about the Ori. The Priors found out Adria is lying to them like the Ori.

Why didn't all the Priors self combust?
