Fight against Sea people when the Pillar of Civilization is collapsed if challenging. And fight manually is harder than that.

In a quick note of interest, What if Sea Peoples identity resembles TW Attila's concept? 

 'You must fight MANUALLY if you want to wipe out the Attila' -and It was horror of nightmare.-

It must be the most torturing part of TW history. Hope Sophia try this in next patch.
